Hard Proof
Hard proofing, also known as hard-copy proofing, is a digitally printed inkjet sample used to review a print job before proceeding with the full production run. While the actual job will be printed on an offset press, a hard proof serves as a vital tool for checking color accuracy and content layout.
A hard proof provides a page-by-page representation of the design but is not bound like the final product. It allows you to spot potential issues with images, logos, and text, ensuring everything is in place before moving forward. However, it’s important to note that a hard proof is not printed on the same paper stock as the final product and does not include binding or finishing elements like lamination or spot UV.
For reviewing the paper quality and binding processes, we recommend using a dummy—a physical mock-up of the final product. Combining hard proofs with a dummy gives clients a comprehensive preview of their project and ensures a polished result.

Hard proof is produced by our Epson inkjet digital proofing machines. These use the GMG color proof system to control the hard proof color. The Epson proof is calibrated to international standards to match offset litho presses. The calibration is checked regularly to ensure the highest standards of color control are maintained. The GMG color proof system reproduces color with 95% accuracy. Offset litho presses are run to tight color control standards and the GMG proofing system is fingerprinted to match these characteristics.
The pdf files used are the same as for the final print run. They are passed through a different color control system to accurately replicate the press colors.
Why Do We Do Hard Proof?
Hard proofing is a cost-effective way to review a print job before proceeding with the full production run. Unlike PDF proofs, hard proofs offer a more accurate representation of colors, thanks to precise color calibration. They also make it easier to review text, logos, and images, providing a tangible way to identify and address any issues before printing. Hard proofs are created before printing plates are made, allowing clients to check the design and make corrections at an early stage. This can save significant costs compared to fixing errors after the print run has begun. For jobs where color accuracy is critical, such as high-end marketing materials, hard proofs are particularly valuable.
It’s important to note that hard proofs are typically calibrated for standard coated papers, so colors may shift slightly when printed on uncoated or specialty paper stocks. Understanding these limitations is key to using hard proofs effectively. For example, if your job requires precise color matching on uncoated or colored paper, an offset-printed sample might be a better option than a soft proof (pdf proof).
Many simple projects, such as flyers or handouts where color isn’t a priority, can rely solely on soft proofing (PDF proofs). PDF proofs accurately display layout and content but lack the color precision of hard proofs.
When special colors or uncoated papers are involved, offset-printed samples may be necessary to achieve the desired results. Ultimately, the choice between hard proofing, soft proofing, or offset sampling depends on the budget, materials, and expectations for each project. By carefully considering these factors, you can select the proofing method that ensures the best outcome for your print job.

Hard Proofing vs Normal Printing
Hard proofing is a reliable tool for checking both content and color accuracy before proceeding with the final print run. The digital files used to create the hard proof are the same as those used for the offset press, processed through the same RIP (Raster Image Processor). This ensures that the hard proof provides an accurate representation of the final print. However, the normal print run is produced on the actual paper stock specified for the project.
Hard proofs are created using a digital inkjet proofing machine on specially calibrated proofing paper. This paper is designed to closely replicate the colors produced by offset litho printing, ensuring an accurate preview of the final results. However, it is important to note that standard offset printing uses a variety of inks, including cyan, magenta, yellow, and black (CMYK), as well as special Pantone and other custom colors.
Additionally, offset printing is performed on a wide range of paper stocks and boards with varying weights, textures, and finishes. While hard proofing is highly accurate for color checking, there may be slight differences in color when the final product is printed on the specified paper stock.
Hard proofs are an essential step in ensuring your print project meets your expectations for content and color before moving to full production.
