To get a closer look at how the paper works, let's inspect the different layers:
1. Base layer: This first layer provides the paper template on which to place layers of crystals. This layer can also have an adhesive back, as with the Polaroid PoGo instant mobile printer.
2. Cyan imaging layer: an image-forming layer that releases a cyan-colored dye when activated at a lower temperature for a long time.
3. Magenta imaging layer: the layer that releases magenta dye when activated at a medium temperature for a medium amount of time.
4. Yellow imaging layer: This layer releases yellow dye when activated at a high temperature for a short amount of time.
5. Overcoat layer: Last, but not least, is this protective layer of clear polymer that seals the paper, which allows it to resist damage from light, heat and water. This layer lends the photo a traditional glossy feel.
As the paper goes through the thermal printhead, the color activated depends on the printhead's temperature and time of application. For example, if the printer needs to activate magenta alone, the heat applied will not be hot enough to activate yellow crystals and won't be applied long enough to activate cyan crystals.The "lower" temperatures and "longer" amounts of time used on these printers are really neither low nor long -- temperatures are hot, ranging from 212 to 392 degrees Fahrenheit (100 to 200 degrees Celsius), and printing one line takes only 16 milliseconds [source: Clarence].
Different mixtures of cyan, magenta and yellow can yield all the colors that you need to print a quality image.
Nasim jezikom receno, kolorni kristali su postavljeni slojevito, jedan preko drugor i to po osnovnom stamparskom rasporedu. Svaki od kristala reaguje samo na odredjeni temperaturni opseg, a od duzine tretiranja zavisi koliki ce intenzitet boje reflektovati 1%-100%.
Kako se dobijaju razlicite nijanse?
Jedna stampana linija se prvo tretira temperaturnim opsegom za Cyan u vremenu jednakom intenzitetu te boje, zatim se ista ta linija tretira drugim temperaturnim osezima u potrebnim vremenskim duzinama. Na taj nacin dobijamo razlicite nijanse, slojevi su transparentni, reflektovana svetlost se mesa i oko dobija informaciju o boji.
Na jednoj od stranica sajta su objasnjene prednosti i mane. Prednosti velicina i jos po nesto, a mana ne otpornost fotografija na vlagu i nedovoljan intenzitet boja na fotografiji ( ovo za boje su naveli profesionalci, a njihovi kriterijumi su razliciti od prosecnog korisnika), navodno fotografije deluju isprano. Ovo ne treba da cudi, jer nedostaje cisto crni sloj. Jeste da se crna moze dobiti mesanjem ove tri, ali nije to to.
Velicina je 5.08 x 7.62cm.
Debljina: Ako se radi o fotografijama, mozes ocekivati deblinu od 160 - 200 gr/m^2.
Pozdrav.
