Trükipinnale

Trükipinnale is an Estonian term used to describe ink, toner or coating being deposited onto a printing surface. The form is the allative case of trükipind, indicating direction toward the surface. In printing literature, it refers to the interface where the printing material meets the substrate that receives the image or text.

In practice, trükipinnale interactions determine adhesion, durability and print quality. Various printing methods rely on effective transfer to the printing surface, including offset lithography, digital inkjet, flexography, screen printing and thermal transfer. Achieving good results depends on selecting compatible inks and coatings and ensuring the substrate surface is suitable for reception of the print.

Surface preparation and material compatibility are central to successful trükipinnale performance. Common preparation steps include cleaning, degreasing and drying, as well as surface energy modification such as corona or plasma treatment to improve ink spread and adhesion. Substrates commonly involved include paper and cardboard, plastic films, metals and textiles. Inks and coatings may be water-based, solvent-based or UV-curable, and drying or curing conditions play a key role in securing adhesion to the printing surface.

Quality considerations related to trükipinnale include adhesion strength, color fidelity, dot gain, and resistance to abrasion or smudging. Process control often involves measuring surface energy, cleanliness, and compatibility of ink with the substrate, as well as post-print finishing and coatings that affect long-term performance on the printing surface.
