Computer-to-Plate Printing 

ENGINEERING NEWS RECORD NOW ACCEPTS 

DIGITAL AD FILES 

Computer-to-Plate (CTP) – digital workflow increases print quality of the ads, 

enables greater efficiency in the production process, and eliminates film – 

ultimately helping the environment. 

TIFF/IT–P1 is the preferred and the most reliable file format, but we also 

accept PDF TM and PostScript TM . In 2001, Engineering News Record adopted the 

DDAP (Digital Distribution of Advertising for Publications) recommended 

guidelines for creating PDF TM and PostScript TM . Within this booklet you will find 

step-by-step instructions based on these guidelines. Adherence to them will 

help ensure the proper reproduction of your ad. To find a TIFF/IT-P1, PDF TM or 

PostScript TM vendor in your area, refer to the DDAP DAD (Digital Ad 

Database) list of providers at http://www.ddap.org/dad/dad.pl.To learn more 

about the DDAP, visit their web site at http://www.DDAP.org. 

Do not submit application files and native files (QuarkXPress TM , Adobe 

Illustrator®, Adobe Pagemaker®, Adobe Photoshop®, etc.) which by 

themselves are not predictable.

TIFF/IT-P1 Specifications 

TIFF/IT-P1 resides in the raster world, meaning that the linework (lw) portion is 

“mapped” before the file is distributed. This file tends to be very reliable 

because the RIP (raster image processor) will simply follow this map. Many 

hardware configurations are now available to create TIFF/IT-P1 files. 

To find a TIFF/IT-P1 vendor in your area, refer to the DDAP DAD (Digital Ad 

Database) list of providers at http://www.ddap.org/dad/dad.pl. 

TIFF/IT-P1 FILE REQUIREMENTS: 

• File should contain at least three of the following components: 

Final Page File 

FP 

Continuous Tone File 

CT 

Linework File 

LW 

High Resolution Component File (optional) 

HC 

• Spot colors should reside in a separate TIFF/IT-P1 file set 

RESOLUTIONS: 

Continuous tone (CT) = RES 12 dpm (300 dpi) 

Linework File (LW) = RES 63 dpm (1600 dpi) and should not exceed RES 100 

dpm (2540 dpi) 

Note: Final output of all ENR pages will be at 1600 dpi/63 dpm

PDF TM Specifications 

PDF TM (Portable Document Format) tends to reside in the vector world. This 

suggests that they are “descriptive” files, based on Adobe’s proprietary PDF TM 

language. The RIP “interprets” the file based on the information contained 

within the “description”. Most desktop applications require the creation of a 

PostScript TM file before a PDF TM can be generated. PDF TM offers advantages 

over PostScript TM as they are generally smaller in file size, easy to view, and are 

more reliable. In 2001, Engineering News Record adopted the DDAP (Digital 

Distribution of Advertising for Publications) recommended guidelines for creating 

PDF TM files. It is imperative to follow the DDAP recommended guidelines 

as well as Engineering News Record’s specifications when creating both the 

PostScript TM and PDF TM files. All of the guidelines, procedures and specifications 

you will need are provided in this booklet. 

Preflighting PDF TM files before delivering them to Engineering News Record is 

highly recommended. Pitstop, by Enfocus, is an application which will check 

PDF TM files against user definable criteria. To purchase Pitstop online, visit the 

Enfocus web site at http://www.enfocus.com/store/store.htm. 

PDF TM FILE REQUIREMENTS: 

• PDF TM files must be created with Acrobat TM Distiller TM 4.05 or higher using the 

DDAP Distiller TM Job Options and the instructions provided in this booklet. 

• Vignettes created in Adobe Illustrator® using the “Gradient Tool” and 

“Gradient Mesh Tool” are NOT accepted due to a known limitation with Adobe 

Acrobat PDF 1.2 files. Vignettes created in Illustrator® with the “Blend Tool” 

are accepted. (Note: Adobe Photoshop® is the most recommended application 

for creating vignettes.) 

• Scanned images must be high resolution (300 dpi), CMYK (no spot colors) in 

TIFF or EPS format. 

• All fonts must be included and be Type 1 or 3 (no Truetype). 

RESOLUTIONS: 

Scanned images = 300 dpi/12 dpm or more

PostScript TM Specifications 

PostScript TM tends to reside in the vector world. This suggests that they are 

“descriptive” files, based on Adobe’s proprietary language. The RIP “interprets” 

the file based on the information contained within the “description”. In 2001, 

Engineering News Record adopted the DDAP (Digital Distribution of Advertising 

for Publications) recommended guidelines for creating PostScript TM files. It is 

imperative to follow the DDAP recommended guidelines as well as Engineering 

News Record’s specifications when creating PostScript TM files. All of the guidelines, 

procedures and specifications you will need are provided in this booklet. 

Preflighting PostScript TM files before delivering them to Engineering News 

Record is highly recommended. FlightCheck®, by Markzware, is an application 

which will check PostScript TM files against user definable criteria. To purchase 

FlightCheck® online, visit the Markzware web site at
