Design Guidelines
Ready to submit your designs to BigiNagi? that's wonderful! Here are some design guidelines to keep in mind.
File Size
A low-quality design will always produce a low-quality print. Make sure your designs look great when you’re creating them and avoid this problem!
Generally speaking, digital artwork will always look sharper than a photo. If you have the choice, stick to digital vector artwork, rather than photos.
Targeting t-shirts, below are the common print sizes that you can aim for when preparing you designs.

Print Colours
The printing color range is more limited than what you will see on your computer screen. Vivid print colors won’t typically come through, so be careful about making this a central part of your design or idea.
We accept files with various color spaces, but our system does all operations in RGB. If you upload a CMYK file, be aware that our system will convert it to RGB and the colors might shift significantly.
The red area is the approximate safe color range.
Computers don’t interpret the entire range of ‘visible’ light. While this is theoretically possible, certain technological limitations prohibit a computer from having the same scope as the human eye. So, while a person might see a certain shade of color, a computer will have a slightly downgraded visualization of the same.
This can be explained by understanding that computers use an ‘additive’ system which combines red, green, and blue (RGB) together to form the desired print color. Even while the computer itself holds an inferior version, the perfect print colors are still emitted from the screen in the shade our eyes are familiar with.
RGB vs CMYK

Print colors (CMYK):
When someone creates a design, or uploads a piece of artwork with various print colors, that picture is stored in computer software as RGB. However, that RGB format must be translated into CMYK before the design in question can be printed. This is because, instead of a screen projecting various print colors, the tints we perceive on a garment are only the reflected wavelengths of visible light.
