Preparing Your Files
Can you print my image all the way to the edges?
If you want your images to go straight to the edge of your prints, be sure to leave at least an 1/8” of “extra image” (a bleed) around the borders. This will prevent any unwanted borders from showing around your image.

What resolution should my image be?
If your image is a bitmap/raster image, you must provide an image with a high enough resolution or else your print will appear fuzzy or jagged. We recommend a resolution of at least 150 dpi.

What file formats do you accept?

A Note About Your Monitor
If you are serious about the colors printed from your images, it is highly recommended that you calibrate your monitors to display colors accurately.

The problem is that most computers default to about 2.2 Gamma at 6500K, which is “hot” and would give the images on-screen a bright bluish cast. If your monitor allows the adjustment, we recommend settings of 1.8 Gamma at 5000 Kelvin which can approximate printed images relatively closely.

How should I name my files?

Why CMYK and not RGB?
With over 16 million colors to choose from, RGB is the colorspace of choice for most people who work on images and graphics displayed on-screen. RGB combines all that color with the light emitted from your screen, to create all the brilliant graphics you see on websites, multimedia presentations, and even television. It is because of this emitted light, that RGB appears brilliant on screen, but dull on paper.

CMYK is a process that prints four colors as miniscule dots on paper that when combined will produce the illusion of an entire image. Printed colors are dependant on reflective light, as opposed to the emissive light from on-screen. Because RGB does utilize this factor of “luminance” some RGB colors can only be loosely interpreted in print.

In short, CMYK is a full color process that is specifically for print. In fact, chances are if you see it in print, it was printed in CMYK.

How do I choose CMYK "safe" colors?
To ensure that that colors that you use in your images are within the CMYK color gamut, choose from one of the predefined palettes: Pantone process coated colors, Pantone solid to process coated colors, Trumatch, Toyo, or Focoltone.

Can you convert my images to CMYK for me?
Although it is possible to receive files as RGB and have them automatically converted to the CMYK colorspace, it is in your best interest to convert the images yourself to see how it will look like once the conversion to CMYK is done. There are minute changes to how an image appears once it is converted to CMYK. Doing the conversion yourself allows you the opportunity to tweak your image as you see fit in CMYK prior to being printed.

Note that the difference can really only be seen in images with very rich colors. The conversion is barely noticeable in photographs.

If you are unable to make this conversion yourself, we can make a best effort attempt to convert your images to CMYK for you free of charge. For most people, the conversion doesn’t introduce any differences they would care about. So if you are NOT particular about color accuracy, you may send us your file in any colorspace.
