These suggested minimums are for each design. As long the print is the same, your minimum order can contain a mix of garments and colours. White garments don't require a "base" therefore the minimums are lower.
Minimums and pricing is for that specific design and print colour. You are charged for the total quantities for that print colour. Example : A one colour white print on 30 black t-shirts in assorted adult sizes will be the same price as ordering 15 black t-shirts and 15 grey marle t-shirts.
There are three groups when it comes to orders. Adults, Youth and lastly Kids. The quantities must meet the minimums for that specific group. Example : A four colour print on coloured t-shirts must have a total of 50 units across youth sizes.
