Canvas Quality for coating

Canvas Types and their Impact on Printing Sharpness and on the Varnish Coating Success

There are different types of canvas for printing and their effect on the image sharpness is measured by various features of the canvas.

The most important feature that can affect the Varnish Coating is the density and thickness of the canvas’s cotton fibers weaving and its whitening coating.

The recommended canvas is the smooth one without any dents and holes of the fibers weaving, which are created as a result of the warp and weft weaving method, another recommended canvas is the one with the smooth whitening coating without texture.

The Varnish can not always fill the deep dents when using a canvas with large and deep dents and covers it with Varnish, and therefore the dints are actually half full with liquid, and hence there is a reflecting in the dints, which makes the canvas printing to reflect inside the dint itself between the dint’s wall sides so it can appear as small air bubbles, or a kind of shiny and rough surface view from the side.

In order to prevent such case, it is important to make sure the liquid varnish coating is well covering the canvas face and fill the dints over the canvas as illustrated before you.
