The most important property of blockout for wide format printing is its opacity. However, there are numbers of other important attributes. As always, we can say – everything matters. And here we go with the list of the important properties of a blockout – material for POS, roll-up & pop-up.
High opacity is super-important! The exposition on a roll-up makes sense only when nothing is backlighting the image. Such effect could be disturbing for the proper reception. This is why every blockout has a light absorbing layer.
Long durability without shrinkage or curling
No shrinkage and no curling. When we present our print, an intention usually is that the image remains flat. In addition, that it doesn’t curl along the edges.
Long durability. This property is simply a cost saver. Usually the roll-up, pop-up & POS solutions are used with some longer term in mind. Therefore, we should always choose the most reliant large format printing media.
Real freedom in choosing the technology, comfort with high-quality printing results
Light surface. In order to create bright reproductions, it requires a light substrate. On one hand the blockout must absorb the backlight, while its front must remain white like a snow. Than and only than the colors can be lifelike and vivid.
High-quality print. Precision, resolution and color saturation are one thing. The other is that physical properties of the medium remain always the same. It is especially important when it comes to large productions. The jobs where repetitiveness is very important. Better players on the market of wide format printing media simply have the ability to keep certain standards.
Printing technology. Many print houses specialize their businesses in order to optimize and make things easier. When it comes to digital print, there are several printing solutions relying on different kinds of inks. Therefore the important property of printing medium is that it is suitable for most of the inks used in digital printing. It guarantees real freedom in choosing the printing technology.
