Moreover, the host 90 provides different parameters to control the operation of the printing system 10. The operation control is usually set in the printer control software, commonly known as "P brush drive. To ensure that the printing system 10 provides high-quality For the image, the operation of the controller 29 must be supplied to the special replaceable ink container 12 installed in the printing system 10. The electric storage device 80 is connected to each replaceable ink container 12 and provides special parameters to the replaceable ink container 12. The ink container 12 is replaced to allow the controller 29 to use these parameters to ensure the reliable operation of the printing system 10 and guarantee high-quality printed images. Figure 10 shows the reaction force in the ink container 12 and the ink drawn from the ink. The comparison of the ink in the container 12. The reaction force or standard pressure shown in Fig. 10 is a negative pressure because this pressure is lower than the atmospheric pressure. In short, the reaction force in the ink container shows a certain amount or This is the negative of the standard pressure. In Figure 10, the reaction force is stated in mercury columns, and the extracted ink is stated in cubic centimeters of ink. Generally speaking, The ink is drawn from the ink container 12, and the reaction force or standard pressure in the ink container tends to increase or become more negative.

V. Description of the invention (19) It is shown that the reaction force in the ink valley device 12 increases, and the amount of droplets ejected from the print head 16 tends to decrease. Once the reaction force reaches the limit operation response force as indicated by the line (please read the matter on the back *, then fill in this page), the increase of the reaction force will reduce the printing quality. The print quality is reduced due to the difference in drop volume. If the difference of 5 drops is sufficient, the output image may be degraded or the color tone of the printed image may be changed. In addition to the loss of print quality, damage to the print head 16 may also occur if the print head 16 is operated for too long under high response conditions. The damage of this print head 16 is caused by the inhalation of the breast milk or the thermal damage caused by the reduced ink flow through the print head 16. One-mouth. The technology of the present invention allows the reaction force in the ink container to be maintained below the limit operation reaction force to prevent degradation of print quality, prevent damage to the print head 16, and make the ink more reusable. Fully drawn from 4 ink volumes II 彳 2. Before discussing the details of the present invention, it is helpful to discuss the static and dynamic reaction force components, which are one of the reasons for reducing the printing quality. The evil reaction force is a reaction force or standard pressure in the ink container 12 and it exists when ink is not drawn from the ink container 12. When the printing system 1G is not printing, a static reaction force or a static state counter-stress exists in the ink container 12. The component of this static reaction force is due to the capillary of the capillary storage element in the ink container 12, and the storage element is a fiber network in a preferred embodiment, which forms a self-sufficient structure. The fiber networks define the spaces or gaps between the fibers, and the fibers form a zigzag pattern. 22 579331 V. Description of the invention (2) Channel. This crack path is formed to have excellent capillary characteristics to keep the ink in the capillary storage element. In an exemplary embodiment, 'when ink is drawn from the tortuous crack path in the capillary storage element, the static reaction force increases from two inches to about six inches of mercury columns. In an exemplary embodiment, the capillary storage element is a bi-component fiber having a polypropylene core material and a polyethylene-to-sheath material. This bi-component fiber has a more detailed description in the U.S. patent application titled "An Ink Storage Tank for an Inkjet Printer", Agent Case No. 10991407, with Davjd Olsen , Jeffrey Pew and David C. Johnson filed in the name of October 29, 1999 and transferred to the assignee of the present invention. The dynamic component of the reaction force is the reaction force in the ink container 12, which is caused by the ink extraction from the ink container 12. From the curve 100, it can be seen that the ink extraction rate constant of 13 cm / min from the ink container 12, The reaction force increases as the amount of ink drawn from the ink container 12 increases. As indicated by curve 98, the component of the dynamic reaction force tends to be higher than the component of the static reaction force. The component of the dynamic reaction force The force is the resistance to the action of the tortuous capillary ink path that the ink is extracted from the capillary storage element. As more ink is extracted from the capillary storage element, the ink must flow through to be extracted from the capillary path of the storage element. The increase of this extraction path tends to increase the reaction in the ink container 12. The paper size is applicable to the Chinese National Standard (CNS) A4 specification (210X297).

The ink comes out of the ink container 12 at a continuous extraction rate of 1 cm3 / minute. When about 27 cm3 is drawn from the ink container 12, the dynamic reaction force indicated by the curve 100 reaches the limit. The operating reaction force is 102 °. When the ink container 12 extracts ink at an extraction rate of 1 cm3 / minute, the reaction force exceeding the limit operation will cause damage to printing quality. The technology of the present invention allows the extraction characteristics to be used to adjust the ink extraction. Rate in order to prevent the printing system 10 from operating under a reaction force exceeding the limit operation. In the illustrated embodiment, the extraction rate is reduced from 彳 cm3 / min to 0_25cm3 / min to allow ink to be more drawn from the ink container. 12. Under the extraction rate of 0.25cm3 / min, until the large About 35cm3 was drawn from the ink container 12 before reaching the limit operation response indicated by curve 102. By adjusting the ink extraction rate from the ink container 12, such as the ink extracted at the 0.25cm3 / minute extraction rate and the The difference between the inks extracted at the 1 cm3 / minute extraction rate can be expressed, and 8 cm3 of ink can be extracted from the ink container 12. The ink extraction rate from the ink container 12 is directly related to the print rate of the print head 16. Many technologies It can be used to reduce the printing rate of the print head 16, thereby reducing the extraction rate from the ink container 12. These technologies include selecting a printing mode from a number of different printing modes. Each printing mode is configured to have a different ink extraction rate. As such, the printing mode or extraction rate is selected based on the ink extraction characteristics of the ink container 12. For example, when a printing mode is printing, when printing each printing frame, 24 paper standards are applicable to the Chinese national standard (Which) A4 specification (21 × 297 mm 丄 A7) 5.

The interruption in this printing tends to reduce the average value of the ink extraction rate from the ink volume 12 in the printing web. Other printing modes can be added, each of which has a different selection time during which the printing is interrupted. As a practical matter, the printing mode can only drive the auxiliary set of available nozzles on the print head. One such printing mode is a two-way printing mode, in which only the 16+ half of the nozzles are printed in the same way. Two continuous way operations. Printing a complete print web, but printing in one direction and halving the ink extraction rate, all printing nozzles in the one direction operation are operating in one direction. The technology of the present invention allows the intended extraction The ink from the ink container 12 is limited to a narrow extraction rate. The extraction rate may be reduced according to the occurrence of an appropriate situation to reduce the ink extraction rate from the ink trough 12, so that the more Much ink can be extracted from the ink container 12. One such case for adjusting the extraction rate is when the reaction force in the ink container reaches a lower limit reaction force value, such as the reaction force at the limit operation. When the bottom limit of the ink is extracted from the ink container 12, the ink extraction rate from the ink container 12 can be reduced. The ink extraction rate is then generated so that a larger amount of ink can be extracted from the ink container 12. Based on the extraction The ink from the ink container or the reaction force in the ink container. The technology of the present invention can be used to select different extraction rates from a number of different printing modes for use in the printing mode.

Description of the Invention (23) ^ " ~, sustainable transformation. FIG. 11 shows a flowchart of an exemplary embodiment of the technology of the present invention. The embodiment is used to adjust the extraction rate to improve the ink extraction from the ink container 12. In this illustrated embodiment, a look-up table is stored in the electric storage device 80 on the ink container 12. This lookup table contains a series of extraction rate values that are relative to the amount of ink extraction from the ink container # 2. Among the stated ink extraction amounts, an extraction rate indicates that in order to increase the ink amount, it can be extracted from the ink container 12. As represented by step 108, the ink container is first inserted into the printing system 10. After insertion, the controller 29 reads the extraction characteristic biometric table, which is stored in the electric storage device 80 connected to the ink container 12. As indicated by step 112, the controller 29 then determines the amount of ink remaining in the ink container 12. The amount of ink remaining in the ink container 12 is stored in an electric storage device 80 connected to the ink container 12, that is, optionally, the controller 29 records the amount of ink printed to determine the amount of ink in the ink container 12. The amount of ink remaining. Assuming that the controller records the amount of ink printed, this information can be stored in the electric storage device 80 such that the electric storage device 80 contains information for determining the amount of ink remaining in the ink container 12. As represented by step 114, the controller 29 then selects a decimation rate based on the ink remaining in the valleyr 12 using the extraction characteristics. In the illustrated embodiment, based on the amount of ink extracted from the ink container 12, the look-up table is used to determine an extraction rate. In order to achieve the desired extraction rate, the controller 29 adjusts the printing mechanism 96 and the print head 26. The paper size applies the Chinese National Standard (CNS) A4 specification (210X297 mm) ^ / 9331 V. Description of the invention (24) 16 of the Operation to select the printing operation to obtain the desired draw rate. In this printing operation, the ink drawn from the ink container i 2 is drawn! It is monitored and the extraction rate is adjusted as needed to improve the extraction of ink from the ink container 12. The single-color ink container shown in FIG. 7 and the three-color ink container shown in FIG. 6 usually have different ink extraction characteristics. The single-color ink container has a large portion in the storage tank 34, and therefore, when the water is pumped, there will be different reaction force characteristics, and each ink is connected to the three-color ink ruler valley "T 12". There are smaller chambers in the colored storage tanks. For this reason, the look-up table connected to the monochrome ink container 12 and the look-up table connected to the three-color ink container 12 may have different values. Fig. 12 is a flowchart of an exemplary embodiment of the technology of the present invention for adjusting the characteristics of the printing press' to give the ink container 12 extraction characteristics, which vary with the ink remaining in the ink container. In an embodiment, the inkjet printing system 1G uses the controller 29 to monitor the ink delivered to the print head 16 by the ink delivery system or ink supply 12. The controller 29 adjusts the print rate of the print head 16 based on the frequency stored on the print medium. This rounding of the print rate of the needle head ensures that no more ink will flow out of the print head 6 than that into the P head 16. If the imbalance between the flow of ink into and out of the print head is large enough, the print head 16 will have a low amount of ink on it to operate properly. The low ink level in the print head 16 is sometimes referred to as "print head scarcity", which may cause a reduction in print quality or reliability of the print head 16. 16 change the water (please read the precautions on the back before filling this page) -installation-: line — 27 paper size suitable for financial and economic standards (⑽) A4 secret (2K) X297 public love)) / 9331 A7 ——___ B7 _ V. Description of the Invention (25) An example technique for adjusting the print rate will now be discussed with reference to FIG. 12. As discussed earlier with regard to Figure 11, an extraction rate is selected based on the amount of ink remaining in the ink container 12 and the extraction characteristics of the ink container. Fig. 12 shows a technique for adjusting the decimation rate or printing rate of the printing system 10 in a printing operation. The extraction rate is adjusted during the printing operation to ensure that the print head 16 does not run out of ink or consume ink to a low amount during the printing operation. Low ink consumption can result in degraded print quality in this printing operation. This reduction in print quality is particularly a problem for large printing presses, which require a large amount of ink ' to form a printed image. If one or more print heads become ink-depleted, the print quality is reduced in the printed image. The shirt image must be reprinted 'and more ink and media are needed, as well as more day-to-day printing to print the second image, thereby increasing the cost of printing. The beginning of the method was to form a part of the output image by printing The single print web is represented by step 116 in FIG. 12. As for the scanning cassette printing system shown in FIG. 1, as indicated by the width 130 in FIG. 13, a printing width is defined as a one-way path by the print head crossing the printing medium. . As indicated by frame 1 32 in FIG. 13, the print medium advances in a patterned manner, and the print heads or Sumida S make a frame 1 32 when they return across the print medium. The print widths 13 and 132 are greatly simplified to show the scanning direction of the print medium. As indicated by step 118, the controller 29 determines the amount of ink ejected from the print head 16. In an exemplary embodiment, the amount of ink ejected from the print head 16 depends on the entire scanning cycle, which includes printing a 28 paper sizes that are applicable to the Chinese National Standard (CNS) A4 specification (2) 0 × 297 mm.

In printing a printing web of 1304, the ejected ink is limited by a drop counting technique. The controller 29 monitors the number of drops ejected while printing the print web 130. The information on the respective drop volume of the special print head is either stored in the controller 29 or the memory 80 set in the print head 16 by itself. The amount of ink or a large amount of ink used to print the printing web 130 is determined by the product of the number of drops printed on the web 13 and the weight or amount of the liquid used for the print head 16. The false δχ output image is a bit consistent, and the amount of ink used or ejected when printing 1 M is approximately equal to the amount of ink used or ejected when printing 13 M. The total amount of ink used to print the print webs 30 and 32 represents the amount of ink flowing from or ejected from the print head 6. As indicated in step 120, the amount of ink supplied to the print head 16 through the ink delivery system or ink supply 12 is then determined. The amount of ink supplied to the print head 16 is determined based on the amount of ink in the ink container 12 and the extraction rate characteristics of the ink container 彳 2. As discussed previously, the ink extraction characteristics change with the ink level in the ink container 12. In the illustrated embodiment, the ink extraction rate or flow rate from the ink container 12 can be determined by a look-up table, which is stored in the memory 80 on the ink valley device 12. The lookup table provides a flow rate of a specified ink amount in the ink container 12. Once the extraction rate is established, the large amount of ink flowing into the print head 16 is the product of the extraction rate and the time required to print a complete circle or print width of 130 and 132. The time required to print a complete cycle depends on the controller 29, which uses the printing width 130 indicated by the reference 5 tiger 134 — a set of 29 at the beginning.

When the scanning cassette can start the reprinted web 132 indicated by reference number 136, the timer is checked by the controller 29. The time to complete the return web 132 can be estimated by estimating from the beginning of the back print web 132 indicated by reference number 136 to the end of the print web 132 indicated by reference number 138. Once the time required to print a complete print cycle or print frames 130 and 132 is determined, the amount of ink flowing into the print head 16 at this time can be determined by the product of the time interval and the extraction rate. A determination is made by the controller 29, not an imbalance that occurs when ink flows into and out of the print head as indicated in step 122. Assuming that more ink is ejected from the print head 16 than ink is supplied to the print head, if the imbalance is too great, a potential problem may occur. As indicated by step 124, if the imbalance is greater than a floor limit, as indicated by step 126, an adjustment can be made to adjust the imbalance. In the illustrated embodiment, the printing system 10 gives an imbalance exceeding a threshold by interrupting the scan box 20 at position 136 before printing the reprinted web 32. Because the scanning cassette 20 is interrupted, when the ink continues to flow into the print head at a constant flow rate, the average value of the ink used in the entire printing cycle of the printing webs 130 and 132 is reduced, thereby allowing the flowing ink to follow Out of the ink. As indicated in step 128, when the print web 132 is completed, the selected interruption time should be sufficient to ensure that the print head 16 does not run out of ink. Once Yuancheng completes the complete printing cycle, the subsequent printing cycle including the printing frames 130 and 132 is performed until the entire image is completed.

Description of the invention (28) — shown in Figure 12 The technology of the present invention has described the giving of the monochrome extraction rate characteristics from the ink valley state 12 to the print head 16. More than one ink color is usually used, for example, for four-color printing, four ink colors are used. As discussed in relation to the illustrative embodiments, the technology of the present invention is performed in each ink color. The selected interruption time is also selected as the largest of the individual interruption times calculated to ensure the ink usage, which is based on the printhead with the largest difference between ink outflow and inflow. The technology of the present invention stores the extraction characteristics on a memory device connected to the ink container 12. The printing system 10 utilizes the extraction characteristics to adjust the operation of the printing system to more fully extract ink from the ink valleyr 12, and to prevent the lack of print heads in printing. By drawing more ink from the ink container 12, the ink container does not need to be placed as usual, thereby reducing the printing cost per page of the printing system 10. Furthermore, 'drawing more ink from this ink container 12 can reduce the amount of ink entering the waste stream. 31 This paper size applies to China National Standard (CNS) A4 specification (210X297 mm).
