Title: When to use 2 white screens
Post by: studog on August 25, 2011, 01:40:33 PM
On an auto at what number of shirts do you use 2 white screens or do you always or never?I am trying to figure out the magic number as to when it is cost effective.  ;)

100 or more is what we have been doing.

about 50. It also depends on how busy we are. If we are pressed for time, we'll burn two for 30 (registration is often not necessary with the film position unit we use).

We do on pretty much every job.  But anytime white is showing we bill it at 2 colors.

Same here unless its a sample for a retailer. If its a sample they are paying for the press time so it goes on the auto.

I've done the math for our shop and it's around 144 shirts for us.  Due to the press speed we can run so many more shirts going around twice than the 15-20 minutes it takes to put another screen into production and reclaim it so our number may seem high to some.  144 with 2 revolutions is only about 18-19 minutes of press time for us and I've figured adding another screen into production takes about that time to produce, setup and reclaim.

I made a chart figuring all this up but I can't find it right now.  It's based on our press speed and screen production/reclaim so it won't really work for everyone.

Would somebody mind telling me what this means? Is this something specific to autos?

If its a light colored garment I'll run one white, on darks 100, above that I 'll break out 2 whites screens if possible.

This refers to a highlight white?

I believe that yes, pretty much printers using autos, deciding when rather than sending shirts around twice for a p-f-p, it's economically advantageous to just run a second white screen after the flash.

They are referring to having 2  white screens to prevent having to have the automatic press revolve around twice to do a PFP of the same design

It really depends on the shop, the nice thing about running them around twice is you can go down and fold them as the next round is circling the press.  We are at around 100 pcs.

I,m getting way off the subject here, but when I print white and use it as an underbase I would rather print it once then a highlight white.  Now if I,m just printing white no top colors I'll go one screen for about 100 maybe a tad more, but anything more like 500pc is like printing a 1000pc.  Alot of white inks have a tad of puff in them even though they say they don't, p/f/p and you'll see the ink rise making it hard sometimes to get a good print with other colors.  Qcm make a very good flat white ink 158 was one of the best white inks I ever used for printing underbase and coverd red shirts like a champ...so what happen they monkeyed around with it until they F'd it up, yeah I know this has nothing to do with the main post ???

I personally don't like the feel of three layers of ink in one area.  I'm guessing you guys that revolve your press on 80 shirt orders don't charge white as two colors?

Any light on dark print we use two screens. No minimum for us.

I bill it as 2 whites.  It's very rare around here to have a dark shirt with only 1 color...that is only when they get a distressed print, or a color that doesn't need a pfp.
