Pinnaprindi kasutamine Eestis loob lisandväärtust puidupõhistele toodetele, eelkõige
turunduslikus aspektis võimaldab see eristuda konkurentsist ja pakkuda kliendile
vastavalt tema soovidele toodete viimistlust. Tänu suurematele pinnatrüki seadmetele on
on võimalik printida ka suurematele pindadele. Sellest lähtuvalt on ettevõtjad hakanud
rohkem huvi tundma pinnaprindi vastu ja katsetama uusi võimalusi, kus pinnaprinti
kasutada. Sealhulgas ka ekstreemtingimustes nagu saunakeskkond.
Magistritöös uuriti pinnaprindi püsivust kahes erinevas saunakeskkonnas. Katsete
läbiviimisel kasutati kliimakappe, mis seadistati standardi järgi saunakeskkondade
tekkeks. Metoodikas mõõdeti ja hinnati kolme muutujat katsekehadel: koloriitsus, läige
ja akrüültindi adhesioon.
Tulemustest selgus, et pinnaprinditud värvispektrid termiliselt töödeldud haaval
muutusid küll koloriitsuse mõõtmise teel, kuid visuaalselt muutusi ei täheldatud. Läike
mõõtmisel selgus, et läikeühik tõusis pinnaprindil soome saunakeskkonnas, kuid vene
saunakeskkonnas alanes. Ristlõikekatse tulemusel halvenes pinnaprinditud akrüültindi
adhesioon vene saunakeskkonnas tunduvalt enam kui soome saunakeskkonnas.
Uurimustöö eesmärgid said täidetud ja katsetulemustel on praktiline väärtus, mida saab
võtta aluseks tulevastesse projektidesse, mis on seotud pinnaprindi kasutamisega
kuumades ja niisketes tingimustes.
The use of digital printing in Estonia creates added value for wood-based products, especially in terms of marketing. It allows them to be distinguished amongst the competitors and offer the customer the desired result. Thanks to larger digital printing equipment, it is also possible to print on larger surfaces. As a result, entrepreneurs have become more interested in digital printing and experimenting with new ways of using it, including extreme coditions, such as the sauna environment. The stability of digital printing in two different sauna environments was studied in the master's thesis. During the experiments, climate cabinets were used, which were set according to the standard for the creation of sauna environments. The methodology measured and evaluated three variables on test specimens: color, gloss, and acrylic ink adhesion through a cross-cut test. The results showed that the digitally printed color spectra on the thermally modified aspen changed by measuring the color, but no visual changes were recorded. When measuring the gloss, it appeared that the gloss unit increased on the digital print in the Finnish sauna environment, but decreased in the Russian sauna environment. As a result of the cross-cut test, the adhesion of digitally printed acrylic ink deteriorated considerably more in the Russian sauna environment than in the Finnish sauna environment. The objectives of the research were achieved and the test results have a practical value that can be used as a basis for future projects related to the use of digital printing in hot and humid conditions.
