9 8 | Printwear O ctO b e r 20 1 4 I'm having a problem getting a white square around my image when I print it. I removed the background in Pho- toshop and saved it as a TIFF, but no matter what I do, some graphics still print the white background. What should I do? There are two reasons this can happen, and both are fixed in Photoshop. The first issue is when your graphic is in CMYK color mode, most RIPs do not support transpar- encies. As a general rule, save your graphic in RGB color mode when you have a transparent background. The second reason is a common mistake during the saving process of a TIFF file. When saving a TIFF file, the window "TIFF Options" pops up. Select the "Save Transparency" box be- fore saving. This is overlooked quite of- ten and puts a white background back on your image. Paul Green, OmniPrint internatiOnal Do I need to pretreat all garments for direct-to-garment? When white ink is used, you must always pretreat the garment. If not, the white ink absorbs into the garment. When it comes to a white T-shirt, you don't need to pre- treat for a commercially acceptable print. However, there are pretreatments made for light garments that add more vibrancy to your printed image and give you a richer solid black. Using this treatment comes down to your personal preference. Paul Green, OmniPrint internatiOnal Should I buy RIP software for my direct-to-garment printer? RIP software controls how a direct-to-garment file is managed before it's sent to the printer. Some enhanced RIP features achieve special color profiles, offer improved gradients, and manage work flow across multiple printers. In most cases, the print driver or packaged printing soft- ware included with the direct-to-garment printer is adequate. However, if you feel you might use any of the additional RIP features, it could be a valuable addition. matthew rhOme, ePsOn america The 2014 Q&A TroubleshooTing guide > direct-to-garment Q&A
