Ultrastream Print Specifications
Maximum paper size: 12"x18" Maximum image area: 11.25"x17.25"
Maximum standard line screen: 140 lpi Maximum line screen with HDI: 200 lpi Minimum highlight dot: 10% Maximum shadow dot: 95% Output Resolution: 812 dpi Standard.


Formats
All continuous tone digital images should be supplied as CMYK composite (single file) EPS or TIFF files. Images should be saved at 200-288 dpi.

Halftones
We recommend halftone screens be set at 144 lines per inch (lpi) This will provide the best results.

Digital Images
Brooks Litho & Digital can accept your original art for scanning. If digital
images are imbedded in your file, you must submit the original image files along with your file.


Scanning
All continuous tone scans should be output for printing at 144 line screen (288 dpi). Higher resolution scans can be used but will increase raster image processing (RIP) time without appreciably improving image quality. HDI (High Definition Imaging*) increases the standard 800 dpi 144 line screen used on the Ultrastream to an apparent 2400 dpi 200 line screen.*
*Requires additional rip time and cost. May not be suitable for all jobs.

Linework
Logos and other linework should be scanned at 800 dpi. RGB & CMYK We
recommend the following parameters when converting RGB to CMYK: 95% black ink limit; Medium GCR; 300% total ink limit.


Image & Paper Sizes
The Ultrastream supports paper sizes up to 12" x 18". The maximum image size is 11.25" x 17.25". Images larger than the maximum image area will be cropped to fit within the designated area. We require that all images be sized before you submit them for production. This will help to avoid cropping problems later on.

Special Colors
The Ultrastream 3000 allows for up to 5 colors to be printed on both sides in one pass. Colors may be the standard CMYK and any spot PMS color except metallics and fluorescent colors. Our IndiChrome ink mixing station provides greater flexibility in your design and more accurate reproduction of spot colors on your jobs. You may still opt to create PMS colors using process tints but we suggest you check our HP Indigo Ultrastream PMS chart prior to specifying values. The chart is available free of charge and can be requested by contacting our customer service department.

Document Set-Up
Pages should be set up as single pages. Files should include manually drawn crops and not Quark automatic cropping. To insure that jobs are trimmed and folded as designed, be certain to include all crop marks and registration marks in your layout. A hard copy dummy showing folding and layout is strongly recommended.

Duplex Printing
Slight variations from sheet-to-sheet positioning could affect two sided printing. There is a nominal variation of less than 2mm. For the best possible results, 100# text is the minimum weight stock we require for duplex printing.

Trapping
Allow 0.3 point trapping in all elements of your design.

Vignettes & Flat Tints
While our Ultrastream 3000 has virtually eliminated the banding problems associated with the earlier E-Print 1000, it should be noted that it is still an electronic piece of equipment and as with all electronic output devices even subtle instances of banding can occur. For this reason we suggest you at least consider the earlier guidelines used for our E-Print 1000 when using vignettes and flat tints. Subtle vignettes have a tendency to band in all electronic output devices. Best results are achieved in vignettes with a tone value change of less than 50%. To achieve satisfactory results in blends, you are advised to introduce "noise". The effect can be achieved with a simple noise filter such as those available in image-editing applications like Adobe PhotoShop. Shorter blends (2-4" or 5-10mm) are recommended. Large, flat background tints can sometimes cause problems. If the design requires it, the maximum recommended tint block area is 8.25" (209.5mm) x 5.8" (147mm). Lighter colors will produce better results. If larger tint areas must be used, a pattern should be introduced into the area to help modulate the color and help the tint maintain a smooth appearance.

Solid Reverse
For solid black areas, we recommend a 40% cyan undercoat to enhance imaging.
