Shade Cloth Ink Printing Instructions for Screenprinters

 




Recent Company News

Preparing shade cloth ink
Mix 10% thickener for water based products into the clear base
For printing white make up 700g clear base with 300g white pigment (standard water based pigment) to make 1Kg white colour.


Printing shade cloth
Two passes of clear base and dry it with hair-dryers for about ten minutes until dry enough to do another coat
Two more passes of clear base and dry it with hair-dryers for about ten minutes until dry enough to do another coat
Then two passes colour and dry it with hair-dryers for about ten minutes until dry enough to do another coat
And another two if necessary to get a good finish or for the lower density shadenet


Usage of shade cloth ink
Usage of base varies depending on the size and coverage of the print and density of the shadenet.
For example we could use from 500g up to 1.5kg per large format print say 2.8m x 1.5m
Right equipment and settings
Use a strong table tack so the shadenet sticks to the table well
Use a 31 screen for good coverage
Use hardener on the screen because the shadenet is rough and the film will break away after use
Use a round squeegee for better coverage
Use a flat squeegee for better edges
Use a snap-off at between 2mm and 5mm


Shade cloth
On the 80% shadenet you may struggle to close all the holes and may have a fine pinprick effect but a good overall finish
On 92% shadenet you will be able to cover all holes and will get a perfect finish (used more for upmarket events)


Tips for screenprinting on shade cloth
With the 80% you might need to take it off the table soon after finishing printing so that it doesn't get stuck to the table
Careful - if the print is still wet and you roll it up it will get damaged and will stick to itself.


Drying the printed shade cloth
Air dry is 48 hours or force dry with hairdryer for about ten minutes so can apply bubble wrap and roll up
Maximum temperature the shadenet can withstand is about 70 degrees
Two big strong hair-dryers will save you time
Heat guns are too strong and will at some stage burn a hole in the shade cloth causing you embarrassment and complications
