Etikete na izdelkih se zlahka obrabijo (prevsem pri vzdrževanju), zapisi na etiketah pa postanejo nečitljivi. Cilj magistrskega dela je bil podati vpliv tiskovnega materiala različne surovinske strukture in konstrukcije na kakovost in obstojnost tiska etiket. Ta raziskava je del obsežnejše raziskave, katere cilj je izdelati priporočila, v katerih bodo zapisani napotki, ki jih je priporočljivo upoštevati pri tiskanju etiket. V preliminarni raziskavi smo pregledali in analizirali splošno stanje etiket na slovenskem trgu. Izbranih šest materialov – trakov, ki jih za tekstilne etikete najpogosteje uporabljajo v podjetju Etiketa tiskarna, d. d., smo v tehniki flekso tiska potiskali z isto tiskarsko barvo, predlogo besedila surovinske sestave z ustrezno velikostjo črkovne vrste in kvadratoma različne rastrske tonske vrednosti. Izdelani so bili pozitivi (beli tekstilni trakovi, potiskani s črno barvo) in negativi (beli tekstilni trakovi, potiskani s črno barvo in belim besedilom) vzorcev. Preiskusili smo osnovne in mehanske lastnosti neobdelanih ter lastnosti večkrat opranih in kemično čiščenih trakov. Preko natisnjenega rastra smo spremljali spremembo barvnega tona opranih in kemično čiščenih vzorcev v primerjavi z neobdelanimi, izračunane so bile barvne razlike. Rezultati raziskave so pokazali, da imajo vsi tiskani trakovi primerljive rezultate, medtem ko se lastnosti trakov po večkratnem pranju in kemičnem čiščenju poslabšajo. Prav tako je bilo ugotovljeno, da so beli tekstilni trakovi (pozitivi) obstojnejši od črnih (negativov) ter da pride pri kemičnem čiščenju do večje spremembe barve vzorcev kot pri večkratnem pranju vzorcev. Rezultati izvedene raziskave bodo podjetju Etiketa tiskarna, d. d., v pomoč pri nadaljnji izbiri materialov za etiketne trakove, predvsem pa vodilo za kakovostnejše tiskanje na trakove.

• Title: Influence of substrate on print quality of sew-in labels

Abstract

Use (wear) and maintenance (washing and drying) of textile products, affect the legibility of printed information on the labels. The aim of master’s thesis was to analyse and evaluate the quality of printed textile labels according to the properties of selected textile ribbons with different properties. The research is a part of a study which purpose is to create recommendations, including instructions recommendable to use in the process of printing. In the preliminary study, we examined and analysed textile labels on the Slovenian market. Six different textile ribbon materials-samples, used in regular label production in Etiketa Žiri, Slovenia, were used. All ribbons were printed in flexographic printing technique. Printed elements were text (example of fibre composition), correspond typeface and two squares, with different tone values. All samples were printed with black (on white ribbons) and white (on black ribbons), solvent-based printing ink. The research was performed on unprinted and printed textile ribbons, before and after washing/dry cleaning procedures. Colour properties of washed and dry cleaned samples were obtained by comparing unwashed/uncleaned printed samples with once and five times washed/dry cleaned ones. From the measured L*, a* and b* colour values the colour difference (ΔE) was calculated. The results have shown that all used unprinted textile ribbon samples had comparable properties, while properties of textile ribbons after printing and washing were deteriorated. Analyses of selected samples also proved that white textile ribbons, printed with black printing ink sustain better quality of labels than black ribbons, printed with white printing ink. Colour changes of dry cleaned samples were higher comparing to washed ones.
