Where is the line for dark vs light garments?

Some are of course obvious... but where is the line?

I know a lot of this is just pure judgment calls... but I'd like to see everyone weigh in on what they PFP or under base vs just rolling with it as if it was a white shirt.

Or are their subtle differences you make to print on a "light" garment that isn't white but you still don't have to under base because of these small tricks/changes to the process?

Ink colour also has some bearing......

in my case this is subjective. If the color has to be PMS matched, it gets an underbase on anything but white. Otherwise it depends on how close we can get without the underbase which in turn is dictated by the ink opacity and garment color. Yellow and gold pretty much always need an underbase, navy and black very rarely. We can get away with max opacity red on med colors, but it has to go through thicker mesh. So if it is a multicolor print and is going wet on wet, this is not an option (to much ink is laid down and it gets spread out by the subsequent colors making for a muddy and bleedy print).

How about posting some info on the particular print(s) and we'll give you some suggestions?

Frog:
ink color, opacity, mesh count.

In the end, it's what you can do. I sometimes run white through a 110 on some medium colored garments and don't flash. (Heck, some do this even on blacks)
I run black on red through a 180

If it's really light color shirts (tan, ash, etc), chances are with all but the most based down dark inks, you will just run them as if the shirts were white.
With light inks, you may just need to go coarser on a screen.

Honestly don't have a particular job.  Don't have any jobs right now that I haven't done before.  This is just in general.

I was putting on a shirt and was looking at the print and wondering at what point do you need to PFP or under base.

I figured it would be a good topic to add to our "knowledge base" here in the newbie section as well as I was sure I'd learn a lot.

So far I'm not disappointed.   Keep em coming!  :)
