ink spots drying in large openings?
« on: April 28, 2014, 07:19:43 PM »
We have a job that we print a couple of times a year for a client. It's a 3 color discharge job. Really big and blocky.

The client is SUPER particular about there being dust or lint or pinholes in the actual print.

However we keep running into little bits of clogged or dried ink in our screens.

We are using one custom mixed blue (all from sericol texcharge), red sericol right out of the bucket, and CCI white discharges.

Any tips on what we can do? We've tried straining it, and still have had issues.

To be clear the screen is getting clogged with what i assume is dried up ink, usually after 1 or two prints

strain it with a piece of 280 or higher mesh

check your buckets for dried ink on the inside edges, it can get into a new mix sometimes.

Whats the best way to strain it? Just put the mesh on top of the container, and squeegee it through?

put the mesh in the screen above image, pour ink, pick up corners of mesh and squeeze down. Rinse out in the sink or drop the mesh into a bucket of water to clean later.

Ironically when I ran an engraving press it was the varnish based inks that I needed to strain and the water-based inks eliminated that messy step
