B., ACAR BÜYÜKPEHLİVAN G., ÖZDEMİR L., URAL E.Carton packagings are graplıical produets vvhich have important effects in inereasing sales and marketing vvith related to design quality and in improving company image, together vvith their carrying and proteeting duties. Hovvever, these are not short term designs like commercial or nevvspaper notices. Many produets keep their design of packagiııg vvithout changing for years. Tlıis is essential for many produets. This kind of produets vvith the design ehanges in packaging is not attraetive for the consumer or they produce conflicts in terms of their safety. Finally, the sales and marketing ehance gets dovvn and llıe company image is badly affeeted. In the present study; samples vvere selected from the most affeeted type of produets in these conditions and the differences betvveen the samples printed in the past and in llıe preseni vvere compared and the general ehanges establislıed. As a result, llıe polential causes and results of ehanges or deformations related to llıe time and the technique used vvere examined and the precautions to be laken vvere presenied.Publication Metadata only Portable document format'ın yapısıve matbaa sektörüne getirmiş olduğu yenilikler(2002-12-30) ÖZDEMİR, LUTFİ; ZELZELE, ÖMER BÜNYAMİN; ACAR BÜYÜKPEHLİVAN, GÜLHAN; ÖZDEMİR L., ACAR BÜYÜKPEHLİVAN G., ZELZELE Ö.

A., ZELZELE Ö. B.Papers are the most commonly used substrates. A printable paper must have certain properties. These properties include surface smoothness, air permeability, surface energy, colour of the paper, opacity, whiteness, light fastness, gloss, and coefficient of elongation under force. In addition, a good printable paper should not allow ink to pass between its two surfaces. After the papers are produced, they are subjected to surface treatments in order to improve the above-mentioned properties and to provide extra specification. Surface treatments include calendering, surface sizing and coating processes. While filling the recesses and protrusions on the surface with the coating process, the paper's affinity for the ink is increased, and the penetration of the ink to the other surface of the paper is prevented. In the coating process basically, a filler is dispersed in a binder. In this study, it is aimed to obtain the highest quality and most printable paper by changing the type of binder used in the coating. In this study, equal amount (5% w/w) titanium dioxide filler was used in all coating formulations. In coating formulations; cationic starch, hydroxy ethyl cellulose and polyvinyl alcohol polymers were used as binders. Binder amounts are adjusted according to optimum viscosity. The obtained coating formulations were coated on the paper surface with a laboratory type coating device. Colour, gloss, surface smoothness, air permeability, surface energy and surface morphology of the coated papers were determined. It was printed with magenta offset printing ink on three different types of paper coated with different binders, using the IGT C1 offset printability test device, under 400 N/m2 pressure printing conditions. Colour and gloss measurements of the prints were made. As a result; It was determined that three different binders improved the printability parameters.
