RESOLUTION - Files, including any images, need to be at least 300 dpi to print clearly, otherwise images may appear fuzzy, distorted or pixellated. Most images found on the web are 72 dpi and are generally not suitable for professional printing.
COLOURS - Files must be CMYK for colours to print accurately. Files that are sent to us using RGB, Pantone, or spot colours will be automatically converted to CMYK which may cause some changes to your colours.
Production printing presses, such as those used here at Design2Express, use different technologies than home/office printers and computer monitors. These should not be used to proof colours as they will not accurately represent what will be printed.
If you require us to match your colours, you must send in an example of the colour to match to (even if we printed it before). However, not all colours are printable using CMYK, and if it is the case that we cannot match your colour we will inform you before printing.
CMYK colour space (subtractive colour) is used for systems where a substrate such as paper or canvas is tinted with various pigments to reflect different portions of the white daylight falling on the surface.
Color paintings, color photography and all color printing processes use the subtractive process to reproduce color. In these cases, the reflective substrate is canvas (paintings) or paper (photographs, prints), which is usually white.
Printing presses use color inks that act as filters and subtract portions of the white light striking the image on paper to produce other colors. Printing inks are transparent, which allows light to pass through to and reflect off of the paper base. It is the paper that reflects any unabsorbed light back to the viewer. The offset printing process uses cyan, magenta and yellow (CMY) process color inks and a fourth ink, black. The black printing ink is designated K (key) to avoid confusion with B for blue.
Subtractive color involves colorants and reflected light. It uses cyan, magenta and yellow pigments or dyes to subtract portions of white light illuminating an object to produce other colors.
RGB colour space (additive colour) is used ONLY for systems which actually create coloured light – e.g. television and computer monitors.
Television and computer monitors create color using the primary colors of light. Each pixel on a monitor screen starts out as black. When the red, green and blue phosphors of a pixel are illuminated simultaneously, that pixel becomes white. This phenomenon is called additive color.
New size of print for the section on bleed in artwork guidelines :
FONTS - If we don't have the font you have used, it may be automatically substituted for an alternative font. To avoid this happening, please embed or outline all the fonts used in your document before sending us the final artwork.
BLEED - Bleed is used to extend an image, colour or line right to the edge of the finished printed piece. For example, if you want your business card background to be entirely blue, you must bleed the blue colour past the edge of the final size of your business card. This prevents a white line down one or more edges of your print, caused by very slight variations in printing and guillotining.
Please include at least 1.8mm bleed on each side of your artwork.
TEXT - Any text must be at least 5mm away from the edges of the finished size.
ARTWORK SIZE - Please refer to file dimension requirements when preparing your file.
