Softproofs

Softproofs are digital representations of how a printed piece will look when produced on a specific printer, with a given paper stock and under standard viewing conditions. They are used in prepress and design workflows to evaluate color, brightness, contrast, and detail without creating physical proofs.

Softproofing relies on color management. In a softproof workflow, the document’s color data is rendered through a proofing profile that models the target printing device and media. The display must be calibrated and gamma-correct, and a controlled viewing environment is recommended. Software tools that support soft proofing, such as Adobe Acrobat, Photoshop, InDesign, and other color-managed applications, can simulate the target printer/paper profile and may offer features like Simulate Paper Color and out-of-gamut warnings to guide adjustments.

Set-up typically involves obtaining ICC profiles for the printer and media (or a device link), selecting the profile as the proofing profile, and enabling proof setup in the software. Designers can compare the soft proof to the original document, adjust colors or tonal values, and re-check until the soft proof aligns with the desired appearance. It is important to note that soft proofs cannot perfectly predict on-press results, since inks, substrate whiteness, dot gain, and press conditions vary.

Industry practice often references standards and guidelines such as SWOP and GRACoL for proofing workflows, along with general display standards like ISO 12646. Softproofs are a cost-effective, iterative step in color-managed production, reducing the need for physical proofs while informing color decisions before printing. However, final verification typically includes an on-press or contract proof when color-critical work is involved.
