| File Preparation
Picture-This can output documents from a wide range of native application files or common file formats. Please refer to "File Submission" for further information on these acceptable files.
The major question facing clients submitting files for large format printing is "What resolution do I need?" To further understand this it is necessary to discuss the two types of computer digital artwork: vector images and rastor images.
Vector Images
Adobe Illustrator, Corel Draw, Macromedia Freehand and Deneba Canvas are all examples of vector based applications. However, they all have the capability to add rastor images to file content. Vector artwork can be scaled infinitely without the loss of detail or quality. Vector based artwork has no resolution (except for placed or embedded rastor images) and does not need any other intervention other than choosing the right colors from the CMYK color palette.
Rastor Images
Rastor images, on the other hand, do have a resolution value which is a critical component of the data to ensure quality output. Adobe Photoshop, Photopaint, Photodeluxe, Corel Painter are all examples of image manipulation or image painting programs that create rastor type images.
It is very important that when working with files from rastor type programs, that the correct resolution is determined from the very beginning. It is not possible to successfully add resolution to an image without suffer quality lose.
Another key factor when talking about resolution is the recognize the difference between input resolution and output resolution.
Document Size
The size of your document should be set to equal the trim size of the final finished piece. Bleeds should be extended a minimum of 1/8 inch (0.125 inch) beyond the trim size of the documents on all appropriate sides.
Trifold Brochures Sizes
Adjust the first folded panel to be 1/16 inch shorter than the other two for 80 lb. text paper and 1/8 inch shorter for 100 lb. text paper.
Images
Include a copy of every placed image in your document(s) including clipart, photos, scans and EPS graphics. DO NOT embed images in your document. DO NOT rename linked files after saving/closing the layout file. Delete any linked files that are not required in your layout.
- Image files should be 300 ppi, 72 ppi files are NOT acceptable
- Convert RBG image files to CMYK before placing the image (offset printing)
- EPS files (DCS off and Binary Encoding selected)
- TIFF files (LZW compression OFF)
Fonts
All fonts used in a document MUST be submitted with the job files. Include all fonts used in the layout AND fonts used in linked files. For Mac, include both screen and postscript fonts and ensure that you have used the proper font face weights (bold, italic, etc.) where appropriate. DO NOT use the application' menu selection for bold or italic styles. For PCs, include all TrueType fonts used.
Rich Black
When working in CMYK and you need to create a dense black color swatch for printing large black areas or black text and objects used in color process printing or backlit film applications use this 'rich black' formula. 60% Cyan, 50% Magenta, 50% Yellow and 100% Black.
