Together.with electrophctography, ln$et is the most developed digital printing

teehnology. lt is eornpletely non-impaet technology, in whieh ink is sprayed directly

from tiny nozzles onto substrate. Other lmportant eharacteristie of lnkjet are liquid inks.

Theyform a single drop, whieh has average radius of 30 pm, while its volume amounts

14 pL.Two basii principles of lnkjet technoloEy are eontinuous and dnop on demand

{DOD) lnkjet. Nowadays, DOD principle is applied more often and it comes in three

different systems: bubble jet, piezo lnkjet and electrostatic lnkjet. ln piezo ln$et, drop is

generated and ejected from the nozzle using defornnation of ink micrachannber"When

*le.tri. signals eome to piezoceramic microelements, it causes the above deforrnation.

These microelements have distortion properties during electric charge activity.

This technology nnay use different inks. One of them are UV inks" Typical

components in UV-lnlget inks are: reaetive diluents (monomers), resins ioligomers),eolorant {pigment), phetoinitiator and additives. [1] White inkjet ink is a fairly new

development within the wide-format grapirics industry. [21

Titanium dioxide is white pigment, mostly r.,rsed in lnkjet inks. There are two

forms of Tior: anatase and rutile. Anatase pigments are mueh more used in liquid

p-rinring lnki due to their softer structure. Rutile pigments have higher refractive

ind"*, t",igt'r*r opacity and somewhat rougher structure. l3l

A nitrogen oxide (No-) is generic term for a group of highly reactive gases'

Most of them are emitted in air in the form of nitic oxide {No) and nitrogen

dioxide (NOr). NO" causes a wlde varlety of health and environmental impacts.

iogether wiitr So- (sulfur dioxide and sulfur trioxide) is the major eontributor to

the "ae id rain". [4, 5]

For high temperature operations, nitregen in the air will react with oxygen t0

forrn oxiJes of nitrogen, NO, and Nor. The resulting NO" coneentration depends

on the highest temperature and how quickly the gas ccols. The higher the

iemperature, the greater is the fornration of N0"" NO is a ealorless gas with virtually

no water solubiliiy. !n the presence of excess oxygen, NO will slowly eos'lvert to

rritrogen dioxide. Nitrogen dioxide !s also a eolorless gas' [61

tightfastness of lnkjet prints is not partie ularly high.That is why this sub.iect was

resea?ched in numerous papers. The same rnkjet ink can't be used for generating

different graphic products, mainly eaused by lcw lightfastness. eclor difference ean

be traeked as a fr.rnetion of speetral energy distribution of UV light sCIuree" lnkjet

prints ean aise be exposed ta different eonditions.

Several papers researehed photoeatalytic oxidation of NO, gases using TiO2'

They have used surfaee specifie teehrriques te !nvestigate the hlO" adsorptive

reaetion at the TiO, substrate sunface" One ef the main eonelusions was that the

reaetion products abserved were lndependent of the tlme of expesulre or of the

hlO" eoReegitration. l7ltolored lnkjet prints changes tone value !n very shont pen'iod. Espeelally if dye

and pigr^nent l1"lkjet !nks wene used" Dye inks Eave better results.The highest ehange

took piur* in yeliew dye ink. lnks that eonta!n pigments showed majen ehanges in

dark cyan, rnagenta and yellow eolor" [8]

Researehes in area of phatoeatalytic reaetion of NG and tdO, and the influenee

of several parameten showed that these pollutants ean affeet tl:e performanee

of stones eontainIng TiOr" The use of TiG, phCItoeatalyst in ecrnbEnatien with

eementatiosrs and othen eenstruetion nnaterlals has shown a favorabEe effcet iri the

3. Rcsults and Discussisn

!n order to deteet ehanges that happened on white ink prints, due to theirexposure to NO" eorytpounds, we were analyzing their eolaration" Figures 2:4 show

ehanges in eolor and lightness, depending CIn number of layers of whitc ink thatwere printed on the substrate.

l-ookinE at the results, it is obviours that the greatest changes, both in colorand lightness oecurred at the first period of the exposure to NO* compounds.Change is greatest between baseline measurement and i " day of exposure toNO- (min. concentration achieved AE,,ur",, r00o/o irv = 34.25; AE,ur",r, 100o/o HV = 42.72;

AE}ur",,, r00o/o HV = i 8.96). After that, prints are stabilizing, and no significant change

was spotted on 3'd and 5'h day of exposure to NO* (max. cor'lcentration achieved

AErraye,rcovoHv = 34.59i AEzr"y",r,i00o/oHV - 42.89;AE1ur"rr, laao/cHy = 2'1"15 ).

ReEarding color ehange, the most stable samples are the ones with only one

layer of white ink applied. After huge primal change, they are experiencing onlyminon changes in color. But, we have a completely different situation when it cornes

Printing white ink on blaek paper substrate is net sufficlent, beeause it daes notempioy in contrast high enough. Forming multiple layers of white ink will generateeolor difference of AE,-r,ayers;100c/o nv = 1 9.59. Optimat number of iayers is proved to betwe. This way, suffieier-lt opaeity will be achleved, and color differenee eompared toone layer of white ink will amount AE,_r,ur",u, 100o/oHV = 14.51

Exposure of thc prints to NO* will result in higher deviation of white prints.The highest ehange will oceur after one day of exposure (AE,_rurers;1.'o/oHV - 34"7A;AEr-rrur",r, loeo/oHV - i0.75). After that, prints stabilized and no further eolor changewas deteeted. Frints printed in different halftone values reaet differently on theexposl",lre of NO*. The higher halftone value, the greater the color d!fferenee is.Unfortunately, increasing the number of layers of lq/hite inks will eause the problemof generating low halftone values (they will be completely lost). Therefore, whiteLED UV lnkjet inks are recomrnended for printing line art illustratlons and largersizes text (over 6 pt).
