G7 is a method of using gray balance to calibrate proofing devices and presses. It results in proofs that match the printed sheet, and in printing that meets the industry-standard GRACoL specification.
We adopted the G7 process in 2007, investing in new equipment, software and training, as well as changing our standard operating procedures in prepress and the pressroom. The process involves measuring color with a spectrophotometer to produce adjustment curves that are applied to the printing plate and to the proofing device. G7 brings scientific precision to color production.
The result is color that is accurate, predictable, and repeatable. Our color proof is a very accurate representation of how the color will look on press, even on uncoated paper.

You never have to think about flattening settings again! We are committed to investing in the technological developments that produce the best possible results. One of these investments is the latest PDF technology in our pre-press system, the RIP (Raster Image Processor), which uses both PostScript and native PDF languages to render the pages. You never have to worry about flattening any transparency effect because our system processes pages from native PDF files with unflattened effects, and converts them directly into the 2,400 dpi image that creates the printing plate.
If you submit PDFs rather than native files, be sure to use a PDF job option that does not flatten. Usually this means choosing a later version of PDF as part of your PDF output options. Use Acrobat 5 at the minimum.
Co-Res is our high-frequency screening technology that produces smoother flesh tones, tints, and gradations, with minimal rosette patterns, moire suppression, and greater image detail compared to traditional halftone screening.
This technology combines the cost-effectiveness of digital presses with the power of databases to enable personalization of your printed piece to either groups or individuals. It can be as simple as addressing in a special font or color, or, both text and images can be changed according to the parameters you set.
Chicago Press has been eco-friendly since before it was fashionable. Our longtime sustainable practices include:
Diverting paper from landfills by recycling all of our waste paper & trimmings
Printing with agri-based inks which are processed from corn, linseed, canola and other oils—in addition to soy. This reduces dependence on petroleum and reduces the VOCs released into the air.
Recycling aluminum plates, saving materials and energy
Actively promoting the use of recycled and chlorine-free papers
Printing computer to plate, saving energy and materials by eliminating film
Promoting recycling and energy-saving practices among our staff
We have also furthered our commitment to the environment by becoming dual certified by the Forest Stewardship Council (FSC) and the Sustainable Forestry Initiative (SFI). These are Chain of Custody certifications. Chain of Custody certification assures customers that they are buying products from responsibly managed forest.
Our signature barcode system prevents problems such as out of order or missing pages. Barcodes are printed on every press form which are read by specialized equipment in the bindery. If the wrong barcode is detected the equipment is stopped automatically.

In-line check weighing
Highly sensitive calibrated inline check weighing scales are incorporated into our packaging lines to verify completeness of shrink-wrapped packages. If a package does not not match in weight down to a single pice of paper not much larger than a post-it note, the package is rejected and the contents are manually verified and corrected.
A series of barcode scanners are incorporated into our inkjet coding, wafer sealing and packaging lines that are connected to the job data on every exam/test book project that we produce. If materials from another project were to get mixed in, the verification system would shut down the line and alert the operator to a possible issue. This allows the operator to manually verify and correct the situation if necessary.
Shrink-wrap packaging and labeling systems
In-line shrink-wrap, package barcode labeling and verification is done on both of our packaging lines.
Customizable barcode inkjet imaging
We are able to image nearly every type of barcode imaginable in size, shape and location on your product. The barcodes are automatically scanned & verified to the job data file to ensure completeness and correctness of your project.
Bar code verification and EPL file creation (Electronic packing list)
An EPL data file is available to you on every barcoded exam that we produce. The file can show barcode/numbering ranges of Individual books, kits, bundles, cartons and pallets. The file is in a convenient .csv format that can be viewed in Excel and input into your own product tracking system.
If desired, the system can be set up to never duplicate a number once used. This will ensure that from administration to administration you will never have two test books with the same barcode number which for some clients is invaluable for product tracking and security.
