Pochemu DTG-printeram nuzhna belaya podlozhka na tyomnykh futbolkakh?
Vse delo v tom, chto chernila CMYK poluprozrachny, a ne kroyushchie. Esli provesti zheltym markerom po beloy bumage, tsvet yarkiy. Na chernoy bumage zheltyy tsvet gasnet, tak kak fon pogloshchaet svet.
V etom rukovodstve my razbiraem fiziku sveta i khimiyu pigmentov, delayushchikh belyy grunt obyazatelnym na tyomnoy odezhde.
Fizika tsveta: Subtraktivnaya model CMYK
Pechat rabotaet po subtraktivnoy modeli CMYK, polnostyu zavisyashchey ot otrazhennogo sveta:
Svet prokhodit skvoz krasitel CMYK, otrazhaetsya ot belogo fona i vosprinimaetsya glazom kak yarkiy tsvet.
Tyomnye tkani pogloshchayut ves svet. Bez belogo grunta chernila CMYK stanovyatsya nevidimymi.
Belye chernila soderzhat chastitsy dioksida titana s vysokim koeffitsientom prelomleniya, sozdayushchie otrazhayushchiy ekran.
Opticheskoe sravnenie: S belym gruntom i bez nego
Raznitsa proillyustrirovana na sleduyushchey skheme:
Skhema otrazheniya i pogloshcheniya sveta
Kak RIP-server generiruet belyy kanal
RIP-programma raspredelyaet kolichestvo belykh chernil potochechno:
1. Plotnaya 100% maska pod yarkie tsveta
Dlya chisto belogo teksta i yarkikh tsvetov nanesetsya maksimalnaya plotnost belogo.
2. Polutona pod temnymi ottenkami
Pod tyomnymi tsvetami belyy sloy umenshaetsya do 30–60%, chtoby risunok ne vyglyadel melovym.
3. Vybivka chernogo (Black Knockout)
Chernye zony risunka ne pechatayutsya, ispolzuya fon samoy futbolki. Eto ekonomit 20–40% belykh chernil.
4. Utyazhka belogo kraya (White Choke)
Belyy sloy szhimaetsya vnutr na 1–3 pikselya, chtoby belyy kray ne vylezal iz-pod tsvetnogo kontura.
