![]() This makes it easier to identify which document to process for a specific page (see File Naming Guidelines).Īll component files and resources (linked EPS and TIFF images) must be embedded. Mark "for position only" (FPO) graphics with "FPO." PDF / PDFx-1a received at a DCS must be single-page only and undamaged. If separations are not provided, mark composite lasers for color breaks and spot color usage. Shingling requirements and/or instructions should be provided in advance.įiles received at an LSC Communications Digital Solution Center (DSC) must be accompanied by a composite laser proof. Type Safety - Leave a safety margin of 3/16 inch for type and other elements not intended to bleed. Fade off tones should equal a 3-4% dot size. Total CMYK overprint densities should not exceed 300%. Consistent resolution within a job is required. Running resolution settings out to the 5th decimal for dots per millimeter will eliminate the risk of introducing artifacts when pages are rendered through some Ripping Systems. LW resolution should be 2400 dpi (94.48819 dpmm). For nested Raster data, the CT resolution should be 300 dpi (11.81102 dpmm). Continuous tone images meant for high-resolution output should be set to an effective resolution greater than or equal to 266 ppi. Any exceptions must be communicated to the LSC Communications facility processing submitted pages. Pages must display with the head of the page at the top of the display. Build all pages at the same orientation and right reading. Any exceptions must be communicated in advance. Output with crop and registration marks turned on, and set the offset to at least 12 points (.1667"). Media box, Art box, or Bounding box must be exactly one inch larger than and set relative to trim size. Build all pages to trim size, and extend the bleed 1/8 inch beyond the document page preferably on all sides or at the very least at head, foot, and front. Text should be saved as (vector) elements of the postscript file or in the line work layer of a raster file format such as Tiff-IT P1 or CT/LW. The result of doing so will cause screened text on output to a postscript-printing device. ![]() ![]() ![]() Do not rasterize the text with pre-press editing software like Adobe Photoshop. All typesetting should be done in an application that will retain the vector properties of the text. Rasterizing the gradient or vignette in Illustrator or Photoshop (at 300 dpi) and then placing it into your layout program as an image will greatly reduce. Vector gradients and vignettes made directly from InDesign or from Illustrator can be very complex to RIP and take excessive time to make plates. InDesign or Illustrator Gradients and Vignettes.Another method is to "Outline" theaffected text or linework while in InDesign. To do this you can build your type on a layer above they image or select the type and choose "object - Arrange - Bring to Front". The simple way to prevent this is to make sure that the type is "above" the image. In doing this it can rasterize type that intersects an image even though this might not be apparent (it may intersect the part of the image that is not visible because it is outside of the picture box mask). When InDesign writes the PostScript file, it must flatten all elements on the page into one layer. ![]() This is the result of transparency flattening, layering, and how the PostScript file is written. Often when type is wrapped around an image, or if it just flows near it, the type can appear fattened or bold when the PDF is created. ![]()
