Supplying finished artwork to Centreprint
If we find any problems in the artwork that you supply to us, we will:
All colours used in your computer monitor, your scanner and your digital camera are made up combinations of the three PRIMARY LIGHT colours Red Green and Blue. Printing machines have to use inks in use different colours to print images. These secondary colours are called Cyan Magenta Yellow and Black. This means that all colours used in any finished artwork supplied should ideally be created as CMYK NOT RGB. All images and photographs should also be converted to CMYK. You are welcome to supply RGB artwork (some programs, such as Microsoft Word only work in RGB) and we will convert to CMYK before use. However, it must be accepted that the colour range available in CMYK (the colour gamut) is far smaller than the range available in RGB (for monitors and screens) so that colours and images will inevitably look duller when printed.
Please ensure that your artwork includes a 2mm bleed area if any part of the images runs to the edge of the finished work. This bleed area is there to ensure that there are no white areas showing (however small) and is trimmed off after printing. If your finished job is 105mm x 148mm, then your finished artwork should be 109mm x 152mm. Never put type or immportant parts of an image too near to the trim edge.
We always send a PDF proof before printing. This gives a rough idea of what the colours will look like, but it is really intended for you to check that no fonts are missing and that no text has reflowed incorrectly. If you request a hard copy proof posted to you, this will be produced on a digital colour laser printer and the colours may or may not match the final printed output.
Creating a solid black
The correct way to print black type is to just print black - i.e., with no other colour behind it. However, if you want a solid area of black to look nice and deep, design as a "rich black". This should be 100% black, with a 40% tint of cyan. This avoids any washed out look to a solid. Important Rich black should never be used for small type, as any small movement in registration will spoil the job.
If you are creating finished artwork yourself, save the images as CMYK EPS or TIFF files. Do not save as JPEG or GIF files. Always SIZE your images as near as possible to the final size used, rather than reducing large images in your page layout program. The finished image should be 300dpi. Do not be tempted to use images from web pages as these are usually 72dpi resolution and will look blurred when printed. Make sure that you DO NOT compress your images using LZW, JPEG or ASCII encoding, or your final result may be in black and white.
Black and white line art should be created or scanned at 800dpi for best results.
We do not look for spelling or grammer mistakes and expect you to have carefully proof-read the job before sending it.
Producing high quality finished artwork for printing is a highly skilled job, calling for many years of experience. We reserve the right to charge for any extra work that we have to do, especially hand-holding for inexperienced designers which can consume many hours of our studio time.
