Smart phone colors vs computer screen colors... tshirts

[TONYC]

I have not opened my store yet. I noticed that the colors on my computer screen of my Tshirt designs are basically how I want them after desgning on a combination of KITTL and CANVA.

However, when I view them on my smartphone, the colors are much too bright and saturated. Being that many people use their smartphone for marketing and purchases, how should I proceed? The designs look less than ideal on a phone. Am I to assume that the phone is showing RGB and I am designing in CMYK?

If the shirts are eventually printed using CMYK and (half) the customers are viewing them in RGB, what is the solution. I want customers to SEE their product, not a skewed version of it.

Thanks for any help!

All screens display in RGB.. Design for the final printed product, you can control that. The way other people calibrate or don’t calibrate their screens is out of your control.. and you’ve demonstrated to yourself how different devices can clearly display differently. Definitely don’t try to design to the preview.. let Zazzle worry about that part. If it’s creating unrealistic expectations, it will be doing it for every product and they will certainly notice.

PenguinPower is right. All screens display in RGB AND practically every device displays colors differently, depending on the settings set by the users. PLUS, PODs work usually with sRGB as the standard color palette and convert the colors via printer-specific color profiles, depending on the printers used to print your design on the different products. PLUS it also depends on the material things are printed on, PLUS on the amount of ink used.

There is no way you can expect a print result matching exactly the screen colors. I personally would stick to sRGB color mode, unless the POD company specifically demands CMYK imagery. This way you can avoid double conversion and also losing colors and saturation on products that are digitally printed with more than 4 colors or use printer-specific color profiles that result in more vivid prints. Perhaps you should also calibrate your monitor so it displays brighter colors. I have calibrated mine so white is a pure white and black a deep black. A good trick is also to head to your local printer, print let's say a digital poster, then compare with your screen and adapt your screen colors so they match well. It's not a 100% guarantee but it helps.
