Our standard dye sublimation print onto display polyester (knitted polyester 205gsm) produces excellent results in terms of resolution and colour vibrancy. However, there are occasions when client wishes to have a double sided image and this cannot be achieved with the standard material because there is no light block between the front and back of the fabric – so the images would interfere with each other.
There are a number of options that we have developed which get around this issue though.
45% show-through
Using our thinnest knitted polyester, 115gsm, we are able to get about 45% print through to reverse when printing on 1 side only. This percentage can appear much higher still when held up to the light and so it depends a little on the environment in which it is used. Of course, this results in a mirror image being seen from the rear of the banner.
95% show- through
By changing some print parameters, we are also able to get much higher print through to reverse on 115gsm knitted polyester – near 100%. This makes it pretty difficult to see which side of the banner was printed and again, the reverse is a mirror image of the front of the banner.
True double sided print
In this case, we make 2 duplicate prints onto 205gsm knitted polyester. We add a light blocking interliner which is glued and sandwiched between the two prints. The three parts are then heat & pressure treated to create a very heavyweight fabric which has exactly the same image front and back without any interference from one to the other. This is quite a breakthrough in fabric printing technology.
