Spot color atramento printing considerations
Rerum ad note cum printing macula color inks:
Angulus quo macula colores texunt
Generalis, macula colores typis in agro et dot processui raro fit, ita angulus color color atramento est fere raro dicitur. Tamen, cum per lucem screen color adnotatione, ibi est quaestio de designing et modificans in screen angle of color color atramento punctis. Itaque collaborative angulo coloris fere XLV gradus translatione (XLV gradus consideretur esse maxime consolatoria angulus percipi per oculum verticem et directionem in directionem ad verticem ad redigendum in directionem ad horizontem et directionem ad redigendum in directionem ad aequalibus et verticalibus potest reducere oculum ad aequalibus et dots).Charta arca archa
Conversio macula colores typis quattuor colores
Multi gravida saepe uti colores in aliquo macula color libraries ad definire colores et color dispensando cum facere graphic consilio et converte in CMYK printing quatuor colores cum separando.
Sunt tres puncta ad note:
Primo macula color Gamut maior quam printing quatuor colore color Gamut in conversione processus, aliquas macula colores non perfecte fidelitatis, sed amittet color notitia
Secundo necesse est eligere "macula color conversionem ad colores" in output lectio aliter ducet ad output errores;
Third, do not think that the CMYK color value ratio displayed next to the spot color number can allow us to reproduce the effect of the spot color with the same CMYK composition of the printed four-color ink (if you can, you don't need spot color) In fact, if it is really concocted, the obtained color will have a big difference in hue.
Macula color captanda
Because the spot color is different from the printing four colors, (the printing four-color ink is overprinted with each other to generate an intercolor, that is, its ink is transparent), the use of the two spot colors usually does not produce an intercolor, intuitively speaking, that will get a very dirty color effect, so define the spot color, generally do not use the overprint method but use keepaway. Hoc cum per loca colores, ut dum alii colores iuxta locum colore graphic, considerandum oportet captanda ne illud sumptus color printingDates Box
Plerumque, macula color printing solet usus excudendi infra tres colores, si quatuor colores requiruntur, CMYK quattuor-color excudendi oportet. Because CMYK four-color printing is basically presented in dot overprinting, and the use of spot colors is basically printed in the field, although usually spot colors are only used in the part of the image, in addition, if the same layout already has a four-color process color, for printing is equivalent to translating one more color, if printing and there is no extra printing unit (such as less than four-color printing press or four-color printing machine), it takes bis ut diu print et sumptus est altior.
