Dylux is a term often heard within the book publishing and printing industries, particularly prepress and printing processes. It refers to an old photographic paper for making proof copies of printed materials.
Dylux paper is a light-sensitive silver-halide-based paper that undergoes diazo reproduction – an innovative printing process in which ultraviolet light is exposed to it before being processed with the chemical developer and fixing solutions to create high-resolution images with text overlay.
Dylux proofs were an indispensable way for publishers, typesetters, and graphic designers to review a book or publication before sending it off for printing. Their visual display allowed for clear visualization of its layout, design, and overall appearance – an invaluable way to make necessary revisions before finalization of publication for printing.
Dylux proofs offered numerous advantages compared to other proofing methods, including faster turnaround time compared to traditional wet proofing methods that required drying time and an accurate preview of what the final printed product would look like.
Though Dylux paper offers numerous advantages, its use has drastically declined due to the evolution of digital printing technology and increased digital proofs, such as PDF or soft proofs, that offer faster ways of reviewing and correcting publications.
Computer-to-plate (CTP) technology has also allowed publishers to directly transfer digital files onto printing plates, eliminating the need for physical proofs – further decreasing demand for Dylux proofs and similar traditional proofing methods.
Dylux proofs may be used less frequently today, but they still hold value within the print industry – especially for those who require physical proofing experience. Publishers and designers may still utilize Dylux proofs to assess color accuracy and overall quality before giving final approval for production.
Dylux photographic paper has long been employed in the book and publishing industries to produce proofs for printed material. Once used extensively to review and make necessary revisions before sending publications for printing, its usage has diminished as digital proofing methods and advances in printing technology become more readily available. However, its appeal still exists for those who prefer physical proofing experiences.
