Abstract
To monitor the alignment of an ink-jet printer (1), a test pattern (4) can be printed on a substrate (3). According to the invention, the substrate (3) comprises a main substrate (31) and an auxiliary substrate (32), the normal patterns being printed on the main substrate (31) and test patterns being printed on the auxiliary substrate (32). In this case, the main substrate (31) and the auxiliary substrate (32) may be made from different materials. A printed test pattern (4) may, in digital form, be compared with an ideal test pattern (4'), and on the basis of this comparison a correction signal is transmitted in order to correct the alignment of the ink-jet printer (1). The correction is preferably carried out to some extent by varying the amplitudes of charging pulses (6) with which the droplets are charged.
Description
The present invention relates to be used to monitor and/or proofread and correct the method for the aligning of ink-jet printer, for print pattern on substrate, it comprises: the ink discharge device that is used to produce ink droplet, be used to the device that makes ink droplet charged, and the arrangement for deflecting that is used for the deflection charged droplets, this method comprises prints at least one pattern.This method is known in practical application.
In practical application, the inkjet-printing device of ink-jet printer comprises one or more printheads, and each printhead comprises one or more ink-jet jets.These ink-jet jets (or nozzle) are pressed the ranks setting.These ink-jet jets produce ink droplet, and these ink droplets have electric charge and are deflected in on-chip desired location in an electric field.Usually, use a plurality of ink droplets (for example 2-15 ink droplet) to be formed on an on-chip pixel.When the printing color pattern, from pixel of ink droplet formation of different ink-jet jets.Cheer and bright is, the needs of ink-jet jet between are relative to each other accurately aimed at, so that obtain good image quality.
If the monitoring and the degree of registration of proofreading and correct the ink-jet jet, may be on substrate the printing test pattern.Yet brought substrate so is not to be suitable for the problem of printing test pattern thereon always.At first, undesirable interference may occur, for example on substrate, have a series of pattern.In addition, if when having printed the substrate sections of test pattern and being cut off, can cause the loss of material.Secondly, the material of substrate may be not suitable for accurately proofreading and correct monitoring on the basis of test pattern.If substrate has more coarse surface, for example common under the situation of textile, can not notice the trickle inaccuracy part of aligning.
In order to overcome these shortcomings, the printing test pattern that once propose to have adopted independent auxiliary substrate.By using an auxiliary substrate, can be independent of other normal pattern and come printing test pattern independently, so just can avoid interference at main on-chip these other patterns.In addition, print quality can not printed the influence of material of (master) substrate of other pattern.For example can be with level and smooth paper as auxiliary substrate.Use this independently shortcoming of auxiliary substrate to be, after the aligning monitoring is finished,, need to replace the auxiliary substrate of proofreading and correct with the substrate of reality if be fit to.Like this, just need additional time and operation.
The objective of the invention is to eliminate above-mentioned shortcoming, and other shortcoming in the prior art, and be provided for monitoring and/method of the aligning of ink-jet printer, can print a test pattern by this method, to obtain monitoring accurately.Further purpose of the present invention is, the method for this specific character is provided, and it has the print procedure of effective least interference.
According to the present invention, be used for a kind of method of this purpose, this method comprises prints at least one pattern, it is characterized in that substrate comprises a main substrate and an auxiliary substrate, and before main substrate face, a test pattern is printed on the auxiliary substrate.When will guaranteeing to print normal image and test pattern, this needn't change substrate.Therefore, this method of very clear employing will considerably be saved time and expense.
Because the present invention is based on easily and apace and monitor the purpose of aiming at, auxiliary substrate must for good and all be retained in the ink-jet printer basically.In ink-jet printer, have in the main substrate, by the printing test pattern, can be in actual print procedure the printing test pattern.Can almost monitor the quality of printing so continuously.
Main substrate can be made with different materials with auxiliary substrate, is for example made by fabric and paper respectively.By this way, can be on level and smooth relatively paper the printing test pattern, even if other pattern is printed on fabric or the more coarse relatively paper.
Main substrate and auxiliary substrate can link together fixed to one anotherly, and for example can be engaged with each other by bonding agent is the form of parallel strip.Main substrate with the advantage of the form that auxiliary substrate is set to be adjacent to each other is: ink discharge device and/or substrate must only be moved beyond a relative little distance, so that the printing test pattern.Yet because generally be not printing test pattern continuously, the major part of auxiliary substrate in this embodiment keeps unused state.
Therefore, advantageously, main substrate and the setting separated from one another of auxiliary substrate, and preferably transmit with different speed.This just makes the great saving to required auxiliary substrate amount become possibility.This method also provides bigger flexibility, because test pattern can be independently to be printed on auxiliary on-chip pattern in this mode.
Although main substrate and auxiliary substrate can adjacently be provided with, wherein auxiliary substrate is not bonded on the main substrate, and they can be advantageously arranged in a crossed manner.The crisscross design to ink-jet printer that transmits provides the bigger free degree.In addition, can obtain to be used for test pattern, because they can be removed from main substrate quickly at early time supervision.
Use the method according to this invention,,, and on the basis of contrast, provide at least one correction signal, finish the correction that ink-jet printer is aimed at described test pattern and desirable test pattern contrast by writing down the test pattern of this printing.Preferably, contrast is carried out with the form of numeral.Can proofread and correct according to time and/or amplitude that correction signal changes the charging pulse offer charging device.
Preferably,, in first proofread and correct to handle, proofread and correct, proofread and correct second and handle, proofread and correct by the time that changes charging pulse by the amplitude that changes charging pulse according to the present invention.Offer correction that the amplitude of the charging pulse of charging device carries out by means of change and whether use an auxiliary substrate irrelevant.
The present invention further provides the device of the aligning that is used to monitor ink-jet printer, comprise: the image recording that is used to write down test pattern, and the compare device, its be used for will record test pattern and hypothesis testing pattern compare and be used for providing correction signal to ink-jet printer according to contrasting.
