File Preparation for Digital Printing
To achieve the best results:
Please remember these design considerations when creating your documents:
Two important points to remember when preparing colour documents for digital printing:
1. 100% colour accuracy is not always possible . At 1UP we calibrate our printing equipment every day in order to maximize colour consistency. However, this does not guarantee that colours will be 100% identical from one day to the next. Colours printed on one stock may look quite different when printed on another stock, and temperature and humidity differences may also cause colour variations. Proofs should always be on the same stock as that to be used. This is especially important when using a specialized stock, such as glossy paper or card stock. If 100% colour accuracy is critical, we do not rely on colour proofs made in advance. We can make arrangements with you to review a colour proof immediately prior to the print run.
2. Colour does not print as displayed on your computer monitor . (RGB vs CMYK) Computer monitors use the three primary colours of Red, Green and Blue (RGB). However, digital printing equipment uses a process based on the colours Cyan, Magenta, Yellow and Black (CMYK). As a result, colours on the printed page will appear different to the colours on your computer monitor. Generally, conversion of an image from RGB to CMYK should be done only once, usually when all manipulation of the image has been completed and it is time to save it for the final time. The range of colours possible in RGB is significantly larger than in CMYK. Some colours will therefore be lost when images are converted to CMYK, and consequently, converting back and forth more than once between RGB and CMYK will significantly reduce the quality of an image. Prior to converting an image from RGB to CMYK, it is a good idea to save a backup copy of the RGB image that can be worked on should your CMYK conversion have less than optimal results. All original artwork and colour blends should be created in CMYK rather than RGB
Scans and raster images should be as close to 1UP recommended resolutions as possible. Images below recommended resolutions may result in blurred images, and dull colours. Images above recommended resolutions will take much longer to process and will only provide a nominal quality improvement.
We recommend that images be within the following resolution ranges when printed at final size:
Small Format Colour (up to 13” x 19”)
Minimum: 200 dpi
Recommended Resolution: 300 dpi Maximum: 600 dpi
Large Format Colour
Minimum: 150 dpi Recommended Resolution: 300 dpi Maximum: 600 dpi
Scanned images are like photographs. The resolution of an image increases when scaled down and decreases when scaled to a larger size.
Our recommended resolutions are all based on the final printed size of the image. If the image is to be printed at twice its original size, the resolution of the original should be twice the recommended resolution. If the image is to be printed at four times the original size of the image, then the original resolution should be four times the recommended resolution.
It is difficult to improve upon an image that is scanned at a low resolution (unless, the image is to be printed at a smaller size). Although Photoshop and some other software programs allow you to increase the resolution of an image, this image manipulation will not always give you good results. The programs do not provide “real resolution” but rather interpolations, or estimates, of what the image might look like at a higher resolution. Usually, quality improvement is minimal and interpolated images can look “flatter” than the originals. For best results, images should be scanned at a resolution equal to the intended resolution of the final output.
There is no automatic notification to 1UP when your files have been uploaded. You will have to let us know each time that you upload files to our FTP site.
