Definitions
- the present invention relates to the manufacture of printing systems and methods for printing. More particularly, the present invention relates to a printing system that is configured to radially print onto a media that rotates in relation to a printing assembly.
- Conventional printing systems typically utilize rectangular based bitmaps.
- a conventional printing system prints onto a standard size rectangular-shaped media along a horizontal axis, for example, and the media is moved along a vertical axis.
- the printing assembly moves across the paper to print an image onto the paper while the paper is held stationary.
- conventional printing systems generally implement movements within a rectangular coordinate system for printing onto media having standard sizes and shapes.
- Fig. 1 depicts a conventional printing system 10 in the form of a typical ink jet printer.
- the printing system 10 includes a print head 102, a roller 106, and an actuator 108.
- the print head 102 is configured for dispensing ink onto a print media 100, representing, for example, a rectangular sheet of paper.
- the actuator 108 is configured for moving the print head 102 across the print media 100.
- the roller 106 is configured for moving the print media 100 under the print head 102.
- the roller 106 moves the print media 100 perpendicularly to the movement of the print head 102. That is, the media 100 travels under the print head 102 along a y-axis 110, and the print head moves over the media 100 along a x-axis 112.
- the movements of the roller 106 and print head 102 generally occur during different time periods.
- the roller 106 initially feeds the media 100 to an initial position under the print head 102. This initial position is typically at the top, left corner of the media 100.
- the roller 106 stops moving the media 100, and the media 100 is immobilized.
- the print head 102 begins to dispense ink across the media 100 at a first y-axis position.
- the print head 102 moves and prints from the left side to the right side of the media.
- the print head 102 typically stops while the roller 106 moves the media 100 to a second position along the y-axis 110.
- the roller 106 moves the media 100 up so that the print head 102 may then print a second line. After the roller 106 repositions the media 100, the print head 102 moves and prints from the right side to the left side of the media 100 at a second y-axis position.
- the print head 102 and associated actuator 108 would necessarily be configured such that space was wasted.
- the actuator 108 would have to be configured to allow printing across the full diameter of the CD. That is, the actuator 108 would necessarily move the print head across the entire diameter of the CD.
- the conventional printer will be configured to print within a rectangular area that encompasses the CD-shaped media.
- the actuator 108 of the conventional printer 100 is necessarily configured to print lines across a maximum width of the media 100. Consequently, the size of the actuator 108 in typical rectangular based printers must typically be configured to move the print head along a maximum width of the media 100.
- Conventional printing systems 10 fail to provide an easy way for printing on non- standard size media, such as a label for a CD-ROM 104 shown in Fig. 1. Being circular in shape and too small and/or irregular in size to be properly handled by the paper handling system of conventional printer systems, the CD label must typically be attached in some manner to another regular-sized media (e.g., a sheet of paper) and fed as such into the conventional printer before printing can occur.
- Conventionally printing systems are also typically not able to handle inflexible media types, such as a CD itself, for example. Even for printers that do not require flexible media, one must typically add a special media holder for each type of non-standard media.
- the non-rectangular shape of the CD label causes difficulties in conventional printing systems, which are typically configured to handle media and print head movements in the rectangular system.
- printing control systems (not shown), which control the movements of the print head 102, typically are not designed to direct the print head across media (e.g., 102) having variable widths along the x-axis 112, such as the circular-shaped CD label 104 of Fig. 1.
- Conventional printers also fail to efficiently utilize all movements of the media 100 for printing. That is, the print head 102 stops dispensing ink onto the media 100, i.e., stops printing as the roller repositions the media 100. Thus, during operation of conventional printers, there may be a period of time during which no printing occurs.

- the optical feedback signal 514 represents a scanned image that was obtained by the optical reader.
- the optical feedback signal 514 may be used to facilitate image manipulation or changes within the computer application 510. For example, a user may overlay another image onto the scanned image, and then output the combined image as the image source 516.
- Fig. 6 is a flowchart illustrating a process 600 for converting a rectangular based bitmap into a polar based bitmap to facilitate radial printing in accordance with one embodiment of the present invention.
- the process 600 may be implemented as rectangular
- the rectangular bitmap represents an image source that is output from a computer application program, for example, and is to be printed onto a media.
- a polar reference point is defined within the rectangular based bitmap, and this polar reference point is mapped to the reference point of the platter
- the reference point of the platter corresponds to, for example, either the OD or the ID of the axis of rotation of the platter 201 and to a selected radius that is defined as having a zero angle or any arbitrary point along line 212.
- the zero angle radius of the platter 201 is defined by any suitable technique.
- the zero angle radius may be defined as a particular radius on the platter 201 that is positioned below the head assembly when the rotation motor is at a particular rotation position.
- a mark on the media e.g., a CD label
- the platter may define the zero angle radius.
- an optical reader may be employed to find the position of the mark and define the zero angle radius.
- the polar reference point may be associated with any data point within the rectangular bitmap. A reference rectangular data point that is associated with the polar reference point may be chosen arbitrarily or may be based on the size and shape of the image, as well as the requirements of the particular application of the present invention.
- a rectangular image may be printed onto a rectangular shaped media that is offset from the center of the platter by choosing a reference data point within the rectangular bitmap that is correspondingly offset from the rectangular image.
- a circular image with a hole in the center may be printed onto a circular shaped media by selecting a reference data point within the rectangular bitmap that corresponds to the center of the hole.
- the user may define a reference point in the rectangular bitmap such that the entire image is printed onto a printable area of the platter 201.
- the user may choose not to print the center of the image by defining the reference point in the rectangular bitmap as the center of the image such that part of the image is not printed. In this example, the center portion of the image may not be printed since the reference point may not be within the printable area.
- a rectangular based data point is obtained from the rectangular bitmap.
- the rectangular data point is obtained in a some kind of logical order. For example, the rectangular data point having the lowest x-value and the lowest y-value is obtained first.
- the rectangular data point is then transformed into polar notation in operation 606.
- Any suitable method may be used for converting the rectangular data point into one or more polar data point. That is, any method may be implemented that converts a rectangular data point that is represented by x and y coordinates into one or more polar data point that is represented by radius and angle coordinates.
- ⁇ may be calculated by arctan (y/x).
- the polar data point is then added to a polar bitmap (e.g., 506) in operation 608.
- the polar bitmap is furnished to the buffer (e.g., 506) in operation 610.
- the buffer may then be accessed by the firing control block (e.g., 508) to print the image source onto the rotating media.
- the firing control block e.g., 508
- each polar data point may be printed prior to obtaining the next rectangular data point from the rectangular bitmap (i.e., there may be no need, in one embodiment to wait until the entire rectangular bitmap is transformed).
- the polar data points may be arranged in the polar bitmap to print an identical image onto all media pieces, or to print different images onto the media pieces (by appropriately referencing the polar reference point to the rectangular reference point).
- a print position look-up table may be implemented to store print positions on the platter, for example, corresponding to the rectangular data points of the image. That is, the print position look-up table includes position data for representing a rectangular data point onto the platter 201.
- the print position look-up table may include print position data for all possible rectangular data points or for a portion of all possible rectangular data points,
- print position data may be stored for one quadrant, and other non-stored quadrant position data is obtained by simple reflection techniques.
- some rectangular data points may have no printed counterparts for distortion correction purposes.
- each rectangular data point does not have to be converted into a polar data point.
- polar data is calculated prior to printing and provided within the print position look-up table.
- print position data for each rectangular data point on the platter 201 is obtained from the print position look-up table. This technique requires less computations during the printing process than the previously described technique of Figure 6 since a polar data point is not generated for each rectangular data point.
- a rectangular address look-up table may be utilized to store addresses of associated rectangular data (e.g., the color of an associated dot) for each print position on the platter 201.
- associated rectangular data e.g., the color of an associated dot
- the associated rectangular data is obtained for the particular dot or print area by referencing the rectangular address look-up table.
- the location of the associated rectangular data in the rectangular bitmap is obtained from the rectangular address look-up table for each dot or print area, the associated rectangular data is then obtained, and the associated rectangular data is printed for the particular dot or print area.
- Operation 606 may also include techniques for correcting printing distortion that may occur in radial printing.
- one type of distortion may occur when more than one dot is printed at one time onto a radial line of the media.
- the dots of a first radial line will not all be printed at a same distance from the dots of an adjacent second radial line.
- the outer dots of two adjacent printed lines are farther apart than the inner dots because of a difference in linear velocity between dots at different radii and the resulting time differences for the ink to reach different dots at different radii.
- two printed lines may diverge such that a gap is present between the two printed lines.
- Fig. 7 is a diagrammatic representation of this large swath, radial dependent distortion.
- a swath 714 that may be located near the innermost portion of the platter 201 has two printed lines 702 and 704 that are separated by a radial dependent distance.
- a dot 713 of printed line 702 is separated from a dot 712 of printed line 704 by a distance 706, while a dot 718 of printed line 702 is separated from a dot 720 of printed line 704 by a distance 708.
- the distance 706 between the inner pair of dots is smaller than the distance 708 between the outer pair of dots.
- Fig. 8 is a diagrammatic representation of mismatches between rectangular data points and polar data points along quantized angles. As shown, printed lines 814 and 816 are separated by a minimum predefined angle 806 due to quantization.
- printed lines 814 and 816 cannot reference certain rectangular data points.
- rectangular data points 808, 810, and 812 cannot be exactly matched to any polar data point along printed lines 814 and 816.
- some estimations must be made to map these rectangular data points onto the printed lines 814 and 816.
- rectangular data point 808 is mapped onto polar data point 804 on print line 814
- rectangular data points 810 and 812 are both mapped onto polar data point 802 on print line 816.
- This "mismatch" distortion, as well as the "large swath” distortion may result in a printed image that appears to includes a plurality of white spots or gaps that are inappropriately scattered throughout the printed image.
- the "large swath” distortion may result in "pie-shaped" gaps within a portion of the printed image that is located near the axis of rotation. If the number of gaps or white spots within the printed image are significant, they will likely detract from any other desirable characteristics of the printed image and/or cause the printed image to not look right.
- twisting distortion A third type of distortion that may occur in radial printing is referred to as twisting distortion, which occurs when the ink is deposited at points on the media having various linear velocities, for example, when the media is rotated at a constant angular velocity. For example, for a CD the center of the disk is rotating at a slower linear velocity than the outer edge of the CD. Thus, dispensing the ink at a uniform rate results in a printed image that appears twisted within the inner portion of the image.
- Fig. 9 is a diagrammatic representation of twisting distortion 900 on a CD, for example.
- a CD 904 has a plurality of radially printed lines 902 that have a twisting distortion. Without the twisting distortion, these radially printed portions would appear straight. That is, ink would be dispensed along a radial line of the CD without the twisting distortion effect. The resulting "twisting" distortion in the printed image may be noticeable by the user or may be undetectable, depending on the complexity of the image source.
- Dual conversion distortion is a fourth type of distortion, which is the result of multiplicative errors from conversion processes (e.g., converting the image source into a rectangular bitmap and converting the rectangular bitmap into a polar bitmap).
- the dual conversion distortion results in blurry edges on polygons or alphanumeric characters, for example, since errors in the relative placement of each dot may occur with each conversion of each image pixel into an associated printable polar data point.
- the blurry edges may be acceptable in particular printed images, such as a bitmap image of a photo.
- the dual conversion distortion may result in an unacceptable printed image with unacceptably jagged, blurry text or shapes.
- Figure 10 is a diagrammatic representation of a character "A" that has been converted into a plurality of rectangular dots 1004 and plurality of polar dots 1002.
- a first conversion distortion is present when the "A” is mapped onto a plurality of rectangular dots 1004.
- the "A” has uneven or “ragged” edges, wherein the dots do not align.
- This first distortion is caused by mapping each pixel of the data source to a closest rectangular dot position. This mapping may not necessarily result in smooth edged polygons or alphanumeric characters, for example.
- a second distortion occurs when the rectangular dots 1004 are mapped to polar dots 1002 within a rotated grid. For example, first rectangular dot 1004a is mapped to a first polar dot 1002a.
- a second rectangular dot 1004b must be mapped to a second polar dot (e.g., 1002b) that is positioned lower or higher than the first polar dot 1002a.
- the polar "A" (without correcting for distortion) contains mapping errors inherent in calculating positions for the rectangular dots 1004 of the rectangular "A”, as well as mapping errors inherent in converting the rectangular dots 1004 into polar dots 1002.
- the "A" that is printed onto the rotating media may not appear as sharp or crisp as the image source "A”.
- an "X" in Table 1 represents a potentially effective solution for one of the four above described distortion problems.
- One or more of these distortion solutions may be implemented, alone or in combination, in the present invention depending upon the particular application requirements.
- the radial printer may be configured to print with a relatively high resolution such that the large swath, mismatch, and dual conversion distortions are significantly reduced or de-emphasized.
- the mismatch distortion may be reduced with a relatively high resolution since the rectangular data points may be more accurately mapped to a larger pool of polar data points.
- the large swath and dual conversion distortion may be undetectable at relatively high resolutions. That is, gaps between printed dots or areas may not be noticeable if the printed dots are spaced closer together.
- An effective way to increase printing resolution is to increase the capabilities of the head assembly, e.g., a higher dots per inch (dpi) capability.
- Another technique for increasing the resolution in one direction is to permanently angle the print head such that more dots may be printed per radius, for example.
- a linear motor with optical feedback to detect the print assembly's radial position may be utilized to synthetically enhance resolution by angling the sensors that detect the print assembly's position. In other words, the angled sensors of the print assembly would allow a relatively high resolution for print assembly position.
- Another technique or configuration for increasing resolution is to implement a stepper motor that is capable of moving the print assembly in relatively small steps or increments.
- the angular resolution may be increased to reduce the large swath, mismatch, and dual conversion distortions.
- the angular resolution may be increased such that the image source is printed on the media after one full rotation of the print head, and a second rotation of the print head is then used to fill in any unwanted gaps caused by large swath, mismatch, or dual conversion distortion. That is, for the second rotation, the print head is offset from the previous location of the print head during the first rotation.
- a 30 second arc offset may be utilized for the second rotation for printing between the dots printed during the first rotation.
- This method is especially advantageous when there is a limit to how fast ink may be dispensed for a given rotation speed. For example, if ink can only be dispensed every 1 minute of arc, a second print rotation that is offset from a first print rotation allows for finer resolution between dots or print areas.
- An alternative to increasing the overall resolution is to only increase the resolution for certain portions of the media.
- a higher inner resolution may be utilized for inner radii to print within gaps that are the result of large swath distortion.
- Another technique for reducing large swath distortion by filling in the gaps between inner radii is to print stripes or other shapes during inner radii printing or during all printing. For example, the printed stripes would help to fill in the gaps from large swath distortion. Stripes may be achieved by increasing the ink dispensement timing, for example.
- a solution that may reduce the dual conversion distortion is to implement a custom driver that is capable of accurately converting image shapes into a polar data points.
- the custom driver would include algorithms for converting known shapes (e.g., polygons) into a set of polar data points with substantially the same shape as the shape of the image source. For example, a custom driver may convert a rectangle's corners into polar data points and calculate positions for data points within the remaining square's sides based on the corner's polar data points.
- the present invention may also implement similar linear velocities or relatively slow speeds for each position along the radii to reduce or eliminate the twisting distortion. The linear velocities may be equal or merely similar enough such that the twisting distortion is undetectable by the human eye.
- the time between the ink dispensement and the ink contacting the media would not substantially vary with different radii distances. That is, the ink would hit the media after a predictable and constant delay after ink dispensement. Thus, distance between the inner portions of the radii would not be substantially different than the outer portions of the radii, and the printed radii would not appear twisted.
- printing areas may overlap on the media.
- the print dots may be sized such that each dot overlaps with the adjacent printed dot.
- Overlapping print areas may be achieved by any suitable techniques or configurations of the present invention so as to reduce large swath and mismatch distortions.
- the print assembly (and firing control) may be configured to dispense ink in large enough quantities to cause overlap to occur between adjacent print areas.
- a variable firing time may be implemented. That is, ink dispensement may be carefully controlled such that large
- 27 swath and/or twisting distortions are undetectable.
- Large swath and/or twisting distortion effects may be predicted for each dot or printing area of the media and then used to calculate an appropriate ink firing delay such that each dot is printed without any significant or detectable large swath and/or twisting distortion.
- the firing delay may be changed at a constant rate as dots are printed along a radius to reduce the twisting distortion.
- a nozzel firing delay may be chosen for inner dots such that gaps would not be detectable that were due to large swath distortion.
- the present invention is capable of printing onto media having various sizes, shapes, and compositions. That is, since the position of the head assembly 210 is based on each polar based data point corresponding to an associated ink dispensement area on the platter 201, the head assembly 210 is capable of readily dispensing ink onto any media type that is positioned over an associated ink dispensement area.
- the present invention may be used for printing onto a CD or CD label.
- the CD may be placed onto the platter 201, and the platter is then rotated below the head assembly 210. As the CD rotates below the head assembly 210, the print head 302 efficiently dispenses ink onto the rotating CD.
- the present invention may be used for printing on small sized media that are attached to the platter (e.g., by vacuum suctioning) and rotated below the print head 302.
- the present invention also provides a simple mechanism for printing.
- the present invention implements rotational motion, which is achieved with inexpensive components, such as a flywheel device.
- the head assembly may move in a slow steady manner by being incrementally moved along a radial line relative to the rotating media. That is, the present invention has the advantage of efficiently utilizing the substantially continuous rotational movement of the media for printing, as compared with conventional systems that stop printing while the media is moved to a new position below the head assembly.
- the platter 201 provides a relatively stable base for the media
- the media 220 is affixed to a stable rotating platter 201 such that a particular point on the media 220 may be repeatedly rotated to the same position below the head assembly 210.
- the relative stability of the media 220 allows the head assembly
- the relative stability of the media 220 allows the head assembly 210 to accurately print in sectors, for example, with few registration problems. In sum, the relative stability of the media 220 allows for increased printing efficiency and accuracy. Additionally, if the platter 201 of the present invention is configured to have a holding device that affixes a plurality of media 220 onto the platter 201 at one time and a media feeding device that feeds a plurality of media onto the holding device, the present invention will be capable of high speed printing.
