The gap between creatives and the industrial world of graphic arts can be detrimental for both sides. The designer needs to be included in the workflow of the printer when creating proposals for industrial reproduction, as any errors in the preparation, pre-press and delivery processes can result in unforeseen outcomes that affect the final budget.

We will use graphic software—Illustrator, Photoshop, InDesign and Acrobat Distiller—from a professional perspective to recreate the entire workflow of a design studio, advertising agency or textile design studio.



This RAC course allows students to address, in a professional way, the manner in which complex graphics projects are carried out, prepared and delivered; to develop an understanding of how to recognise errors in the delivery process—overprinting, trapping, ink separation, out-of-register elements; to manage spot colours (Pantones); to understand how to analyse the packaging die; and to become familiar with standard printing processes (offset) using the latest innovations.

Students will also learn to prepare the workflow for different final media: paper, screen print, vinyl, canvas, digital print, etc.


1. Digital laboratory

  • Preparing digital images for graphics projects
  • Professional cameras, flatbed scanner, drum scanner
  • Resolutions and line screens: how to determine the appropriate resolution, the right way to increase or decrease it depending on the final medium
  • Digitalisation of different original pieces
  • Opaque: printed, photographic paper, illustrations, transparencies, negatives, etc.
  • Size and resolution
  • Enlargement without loss of quality
  • Bicubic interpolation
  • Resampling
  • Descreening
  • Focus filters
  • Digital reproduction for different paper weights and line screen rulings: offset, rotogravure, newspapers, magazines, art books, screen prints, websites, iPad, iPad Retina, large-scale pieces, canvases.

2. Work strategies for a four-colour printed publication

  • Preparing a project for CMYK printing
  • Preparing images with a colour toning effect in a four-colour printed magazine

  • Formats for export: TIFF, PSD, PDF

3. Planning a project in accordance with the budget

  • Adapting a publication to greyscale, working with black ink
  • Creating monotones with any channel of Cyan, Magenta, Yellow

  • Creating a multichannel
  • Controlling direct inks in the editing program
  • Printing through the PostScript language, Colour separations with CTP
  • Checking whether two inks line up correctly
  • Using Acrobat Distiller to create a PDF for the final delivery
  • Formats for export: EPS/DCS.2.0, PDF, PS, PSD

5. Resolving problems caused by poor management during post-production

  • Properly analysing ink separations
  • Proper management of tints
  • Importing pantones from other programs
  • Working with global colours
  • Converting a pantone to CMYK
