Sorry za latinicata - v momenta sym na PC koeto ima samo BDS, a az sym sviknal s fonetichna klaviatura.

Ne sym chuval termina, no eto kakvo namerih:

"Another innovative feature is the way the laminate has been printed, involving spreading of a laser-sensitive ink so that the variable data can printed at the precise moment of packing, without having to use ink-jet technology." (first link below)

"Thermo-autochrome
Thermo-autochrome printing is most like traditional photographic processing. Thermo-autochrome paper is covered with three hidden layers of light-sensitive ink--cyan, magenta and yellow--each of which is activated at a certain temperature. As the special paper passes through the printer, tiny modules heat up tiny areas of the paper, activating the hidden colours one by one. Then an ultraviolet light passes across the paper, "fixing" the colours--that is, preventing the inactivated ink from developing." (second link below)

Predpolagam, che stava duma za opredeleno pole ot opakovkata, koeto e predvaritelno pokrito s mastilo, chuvstvitelno na lazeren lych, no ustoichivo na obiknowena svetlina. Togava v momenta na opakovane tova pole moje da se skanira s moduliran lazeren lych, pri koeto veroiatno osvetenite mesta stavat cherni, a ostanalata plosht shte si ostane biala (ili prozrachna?).

Pliusovete na takava tehnologia, osobeno pri paketirane na hranitelni produkti, biha bili v slednoto:
1) Modulyt za pechat moje da se integrira v paketirashtata linia i da otpechatva individualni etiketi vkl. tochen gramaj, vreme/data i pr.
2) Pri tova ne se izpolzvat kakvito i da bilo mastila ili himikali (koeto e vinagi problem pri opakovane na hrani). Predpolagam, che sloiat mastilo e laminiran/zapechatan v samata opakovka, i prosto se "proiaviava" chrez lazeren lych.
