Abstract
The invention relates to a digital printer color control method which comprises the following steps: A. before color calibration, first the main optical imaging part of a printer is in a normal state, a laser head, a charger and a PTE lamp are kept cleaned, and pip and a blanket are within a loss range; B. a color standard development step is entered; C. after production is started, the conductivity and density stability of ink shall be kept, a test strip needs to be re-printed one hour after printing and 3 to 4 hours after the printer is idled, if the data exceeds the error range established by hubcast is viewed, and corresponding curve adjustment is carried out. The method mainly solves the technical problems that the traditional consumptive material (photosensitive belt, transfer blanket and the like) reduces the light sensing capability and the transfer capability of the material with the increasing use times so that the color is unstable, can control the color within a certain deviation range within the service life of the consumptive material, and greatly improve the color stability.
Description
Technical field
The present invention relates to the Color Management Technology field of digital printing device, particularly a kind of digital printer color control method.
Background technology
Hp indigopress3050 is the digital offset printing printer of a kind of paper feed type, and it is with the patented technology of Hewlett-Packard---Hewlett-Packard's electric liquid ink technology is combined with the high-velocity electrons imaging, makes and prints high-quality color printing operation.This printer has intuitively user interface, and the active screen print procedure is provided, and can fully understand operation and carry out situation, can accept very large file, and has simplified whole file process.The same with offset printing, the digital color offset printing is being incited somebody to action ink image and is being transferred to blanket from image carrier, is transferred to stock from blanket again, and different from offset printing is that the digital color offset printing is whenever turned around and just can be created a kind of different image without colour separation film or forme.Use embedded rip, can process at the printer station file of postscript or portable document format pdf.
The Indigo3050 digital printer is a highly integrated printing machine, because existing consumptive material (sensitive tape, transfer printing blanket etc.) can reduce along with increasing of access times photoperceptivity and the transfer printing ability of material itself, thereby cause the unstability of color.
Summary of the invention
The object of the present invention is to provide a kind of digital printer color control method, mainly solve existing consumptive material (sensitive tape, transfer printing blankets etc.) meeting reduce photoperceptivity and the transfer printing ability of material itself along with increasing of access times, thereby cause the instable technical problem of color, it can be controlled at color within certain deviation range in the service life of consumptive material, greatly promotes the stability of color.
For addressing the above problem, the present invention is achieved in that
A kind of digital printer color control method adopts Hp indigo3050, it is characterized in that it comprises the steps:
Before A enters colorific adjustment, guarantee that first the main imaging part of printer is in normal condition, laser head, charger, PTE lamp keep clean, and pip and blanket are within exhaustion range;
B enters color standard and formulates step, specifically:
Behind the B1 start heating machine, machine is arranged to external Density Measuring Instrument pattern, and machine is carried out for the first time adjustment of transfer pressure, is adjusted to moderate pressure;
B2 enters calibration---and lut shows calibration;
B3 prints cleaning Zhang Qingjie blanket;
Then B4 enters the typing of color calibration and data;
B5 selects 180dpi, prints than look and opens, and with external Density Measuring Instrument test cmyk four color densities, is adjusted within the normal range (NR);
(k＝1.75~1.80)，m＝1.45~1.50，c＝1.45~1.50，y＝1.05~1.10)
B6 tests dot density and the dot gain rate of each color with external Density Measuring Instrument, insert in the tables of data of computer generation, then presses smoth (smoothed curve) button and makes excess smoothness between each site;
B7 presses print job with chromalin lut (built-in optical Density Calibration lut shows to print) button and does the calibration of 50% site, finishes, and so far the machine lut of machine intimate (printing machine internal contrast table) finishes;
B8 does the standard testing of hubcast (Business Name); 10 of the test-strips that printing hubcast company provides, then choose last, the optical density (OD) instrument scan-data that provides with hubcast enters in the testing software, as the pass printed words occurring by software, expression machine color is within critical field, otherwise the prompting that reports an error then appears, check which color lump goes beyond the scope, then adjust the color curve on the indigo, until the test by hubcast, if the error range deviation that the test-strips that prints and hubcast allow is excessive, then again did the calibration of lut table;
After C enters production, keep the stable of the conductance of printing ink and density, print after 1 hour or machine is idle needs again printing test bar after 3-4 hour, check that data have or not the error range that exceeds the hubcast formulation, and make corresponding curve adjustment.
Described digital printer color control method is characterized in that in the described steps A, and charger, pte lamp use nonwoven to dip in the absolute alcohol wiped clean before start every day, and first week of laser is used nonwoven and gently wiping of absolute alcohol.
Described digital printer color control method, it is characterized in that this method environment for use requires to be: temperature is controlled between 20 to 25 degrees centigrade, and humidity is controlled at 50% to 70%, keeps good ventilated environment.
Described digital printer color control method is characterized in that temperature and humidity control use common air conditioner commonly used, humidifier, dehumidifier.
Advantage of the present invention is as follows:
The stability of the color of printer in this method greatly improves, the misalignment of file printing front and back is controlled within the very little scope, allow those need again printing, the work of reprinting becomes and is easy to, also the file to dtp output brings very large benefit, generally just can reach satisfied effect through simply entangling look.
