Ryerson GCM student Jenna Peters achieves first G7 Grayscale proofer calibration at Ryerson University

Jenna Peters is a third-year student with Ryerson University's School of Graphic Communications Management.
Ryerson Graphic Communications Management student Jenna Peters was the first student in her class to create a pass for G7 Grayscale calibration on the university’s Epson 7900 Inkjet Proofer.

Dr. Abhay Sharma, Professor at Ryerson University’s School of Graphic Communications Management (GCM) and colour management expert, reports that his students are performing G7 colour calibration for proofing and printing. The G7 Method is a procedure used for colour reproduction by matching grayscale colorimetric measurements between printing processes. G7 stands for grayscale plus seven colours – the colours typically used in printing (cyan, magenta, yellow and black) and the additive colours (red, green, and blue). The method is used in many applications such as offset, flexography and gravure, since it utilizes a one-dimensional neutral print density curve (NPDC) to match neutral tonality between two G7-calibrated printing systems.

Jenna Peters was the first student in her GCM class to create a pass for G7 Grayscale calibration on the university’s Epson 7900 inkjet proofer. This was the first time that the new version of Curve software (Curve4), with generous support from Chromix, was used. This was also the first time that Don Hutcheson’s new horizontal format target – P2P51H – was used. Hutcheson is the creator of G7 methodology. Peters generated the required correction in Curve4, and applied it using curves in Photoshop. This was a new project in a new course at the university – GCM 360 Colour Management.

Peters, a third-year student in Ryerson’s School of Graphic Communications Management, commutes to Toronto from Pickering and is studying print media, magazine publishing, sign and display graphics and 3D printing. This is one of many comprehensive and challenging projects that GCM students are undertaking in colour management involving CRPC6, GRACoL, expanded colour gamut, spot colours, colour management for 3D, and many more key areas. GCM professors, instructors and Graphic Arts Magazine congratulate her on this achievement.
