1. the color separation method that a kind of suitable ceramic ink jet prints, it is characterised in that comprise the following steps:

  • Step 1:

    Ceramic ink jet printing single channel linearization test;

    (1) quantity of ink according to 5 ink color passages of ink-jet printer, makes linearisation file, preserves;

    5 inksColor Channel includes C-channel, M passages, Y passages, K channel and Z passages, and the Z passages are Spot Channel, can be according to concrete ceramicsInk-jet demand converts ink color;

    The maximum ink amount of each passage is expressed as 100%;

    The quantity of ink value of 5 ink color passages is chosen by following dot percentage:

    C-channel=3%, 5%, 7%, 10%, 15%, 20%, 30%, 40%, 50%, 60%, 70%, 80%, 90%,95%th, 98%, 100% };

    M passages=3%, 5%, 7%, 10%, 15%, 20%, 30%, 40%, 50%, 60%, 70%, 80%, 90%,95%th, 98%, 100% };

    Y passages=3%, 5%, 7%, 10%, 15%, 20%, 30%, 40%, 50%, 60%, 70%, 80%, 90%,95%th, 98%, 100% };

    K channel=3%, 5%, 7%, 10%, 15%, 20%, 30%, 40%, 50%, 60%, 70%, 80%, 90%,95%th, 98%, 100% };

    Z passages=3%, 5%, 7%, 10%, 15%, 20%, 30%, 40%, 50%, 60%, 70%, 80%, 90%,95%th, 98%, 100% };

    (2) inkjet printing linearisation file, checks the hundred of the tone level situation of each passage, record level appearance after firingRatio, the percentage that described and level occurs is divided to include the percentage F of high light levelstartAnd the percentage F of shadow leveleffective

    (3) as ceramic ink jet printing equipment is, without linearized system, need to carry out linearisation adjustment, adjust in PhotoShopEach passage high light " is exported " value and is set to the F described in step 1 (2) by orderstart

    Each passage shadow " is exported into " value settingFor the F described in step 1 (2)effective

    The process of the linearisation adjustment is referred to and for 5 ink color passage files to be converted into linearisation according to Linear Mapping formulaThe process of file;

    The Linear Mapping formula is:

    K=Feffective-FstartFi=Fstart+ K/99* (i-1) i=1,2 ... 100(4) linear file after ink jet printing and firing are adjusted, checks linear effects;

    Step 2:

    The sampling colour atla that printing firing ceramics ink jet printing ICC make;

    (1) generate multichannel colour atla in the measure tool instruments of ProfileMaker softwares, colour atla totally 440 color lumps,Each color lump is formed by stacking by the default dot area percentage of 5 passages, is corresponded to C-channel, M passages, Y passages, K channel and Z respectively and is led toRoad, the default dot area percentage combination of the passage have following several:

    First, single passage is incremented by from 10%~

    (2) colour atla of collection is carried out into linearisation adjustment in Photoshop, the linearisation adjustment is to utilize PhotoShopEach passage high light " is exported " value and is set to the F described in step 1 (2) by middle adjustment orderstart

    By each passage shadow " output "Value is set to the F described in step 1 (2)effective, preserve;

    (3) the collection colour atla after ink jet printing linearisation adjustment, and high-temperature firing is completed, chamfering, edging polish whole set process.Step 3:

    Using ProfileMaker softwares " multichannel multicolor modules ", couple Eyeone spectrophotometer measurementsCeramic color lump chrominance information after firing, generates ICC multichannel characteristic files;

    Step 4:

    The multichannel characteristic file of generation is stored in into computer " C;

    /Windows/System32/Spool/drivers/In color " files;

    Step 5:

    When carrying out color separation to RGB design documents, in the software of Photoshop CS4 above versions, select " editor-Be converted to configuration file-senior setting " in panel, the ICC multichannels stored in step 4 are selected in multichannel drop-down menuCharacteristic file, click on conversion, you can so that RGB files are converted into suitable color separation file, the color separation file Jing printing fire after,The accurate simulation to design document color can be realized.
