Printify's print provider partners are not all the same. Here are the ways in which they differ:
Product price and the shipping rates
Available product models and variants
Available print areas and their sizes
Print Provider Ranking (reprint ratio, production speed)
Printing equipment and printing methods
Even if they are printing on the same garments and using the same print technology, each print provider will have performed their own unique tests to achieve the desired color output.
Before selecting a print provider to work with, we recommend learning more about them here, as well as on their individual websites.
