Abstract
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.
