I think you experts will answer this quite easily.

I just want to print a white design on a T-shirt.

I think I read somewhere that you have to introduce a small amount of colour or the RIP won't print anything at all - am I correct? If so, what colour do you add - is it just a case of lifting one of the C:0 M:0 Y:0 K:0 figures?

I have seen the issue of white not printing when I edited some text in an existing design and filled it with C:0 M:0 Y:0 K:0 - it didn't print anything! I just checked the design I altered and confirmed the white text that did print was filled C:0 M:0 Y:0 K:5

If you lift one of the figures to introduce some colout, albeit a small amount, does this result in the printer doing a 2nd pass to print the minute amount of colour? I wouldn't want this.

Cheers

John

I don't know your RIP, but with ours, if you have a transparent background, you can choose print white ink only, it doesn't matter what the color of your graphic is. If we don't use that setting, then we have the option of printing 100% white under any color pixel. So you would change the white of your design to 2-3% Black. You might have to RIP the 2 layers and delete the color layer, but I would assume there should be a setting on your RIP somewhere to not have to use this method.

No, it won't you have to put a one in any of the values. This is the only way white will show up..ever

if you feel that the white is too light you can always print a second pass

I change one of the values or in rgb mode change 255 255 255 to 253 253 253. This is still a white and you really cannot tell the diff. However it will see this as color then print a underbase that puts 100% white under each color pixel. Then the color layer puts the 253 white overtop. This results in a 2 pass white. 1 base 1 color. Great coverage. No need to delete files or run same file twice. Different rips have different modes concerning 100% white and underbase.
