Editorial Reviewers
PrinterTools content is reviewed for technical accuracy by two academic specialists from the University of Zagreb. The site's 26 colour-conversion and print tools, 13 printer test pages, and 20 troubleshooting and how-to articles are split between them by topic-fit: colour-science content goes to the colourimetry reviewer, and digital-publishing and workflow content goes to the document-workflow reviewer. Every calculator, blog post, and test page shows the assigned reviewer's name in a byline below the page title.
Reviewers attest to methodology and accuracy within their declared scopes. Site owner Dan Dadovic remains responsible for editorial direction, implementation, and the code itself. The editorial policy and methodology page describe how content is sourced, tested, and revised.

Assoc. Prof. Rahela Kulčar, PhD holds an Associate Professor position at the Faculty of Graphic Arts (GRF), University of Zagreb. Her teaching and research focus on colour science and colourimetry, with particular attention to colour reproduction, colour management workflows, and the physical-chemical behaviour of printing inks.
On PrinterTools her review covers the colour-science surface of the site: all 23 colour-converter tools (RGB, CMYK, HEX, HSL, HSV, Pantone, RAL, NCS), the ink-coverage estimator and image colour-picker, the printer test pages that target colour reproduction (B&W, colour, CMYK channel isolation, RGB, grayscale, individual colours, photo quality, solid black, alignment, nozzle check), and the colour-education and colour-management articles (RGB-vs-CMYK guide, ICC calibration, streak diagnostics, nozzle unclogging).

Prof. Valentina Kirinić, PhD holds a Full Professor position at the Faculty of Organization and Informatics (FOI), University of Zagreb, based in Varaždin. Her teaching includes the "Obrada teksta i slike" (text and image processing) course, and her research covers information literacy, software quality, and digital competencies — the editorial and workflow side of how documents move from source to print.
On PrinterTools her review covers the digital-publishing and document-workflow surface: the Print Utilities tools (DPI calculator, paper size guide, WCAG colour contrast checker), the nine brand-specific test-page guides (HP, Canon, Brother, Epson, DTF, Dell, Lexmark, Samsung, Xerox), workflow and connectivity troubleshooting (printer-not-printing, offline, spooler, blank pages, mobile printing, duplex, inkjet-vs-laser), and the test pages that target typography and document layout (text clarity, bleed and borderless, ruler and dimension).
