3 Questions 1. In Colour Management, when is it better or more appropriate to use Perceptual or Relative Intent? 2. I often used to get some horrible colour casts but these seem to have stopped after I've selected "Off(No Color Adjustment)" for Mode in Media Settings. What makes this better than choosing Epson Standard (srgb) or one of the other options? 3. Is Soft Proofing necessary? I tend to ignore the out-of-gamut warning and the print colours still seem to look ok.

5 Our Goal

6 So how do we get there...

7 Where do we start You take a picture of course! But what s that got to do with how you print? It all starts with your camera settings

8 Everything has it s own Colour Space

9 Colour Space srgb Adobe RGB (1998)

10 So what about monitors and printers? Where do we apply this?

11 and media? Adobe RGB (1998) vs Epson Premium Luster Adobe RGB (1998) vs Epson Archival Matte

12 How do we control the colour?

13 How do we control the colour? Monitor calibration & viewing conditions Software control of your colours Apply correct printer settings

14 Monitor Calibration Lots of different devices available and some monitors will self-calibrate Best to re-calibrate on a monthly basis or when you start a new project Costs vary from 100 up to 1,500 for professional models

15 Printer Calibration / Profiling Some monitor calibrators will also profile your printer In most cases not necessary these days due to calibration at factory and high quality media profiles, but can be useful to create custom profiles for specialist medias and lighting conditions Commercial printers can feature in-line spectrophotometers, this helps when profiling media on rolls and completes the process automatically

16 Viewing Conditions Best to view prints under daylight conditions, or D65 (6,500 kelvin)

17 How do we control the colour? Monitor calibration & viewing conditions Software control of your colours Apply correct printer settings

18 Software Settings Match colour space settings in software to avoid conversion issues if you shoot in Adobe RGB, edit in Adobe RGB

19 Softproofing Available in all Adobe software Applies the printer / media combination profiles to the image on screen allowing you to edit accordingly

20 Softproofing Available in all Adobe software Applies the printer / media combination profiles to the image on screen allowing you to edit accordingly

21 Application Settings Select correct printer Let Photoshop Manage Colors Select correct media profile Use preferred Rendering Intent

22 How do we control the colour? Monitor calibration & viewing conditions Software control of your colours Apply correct printer settings

23 Printer Settings Turn OFF Color Adjustment in the printer driver Will automatically disable if using Adobe CS6 or CC

24 Black Point Compensation What is it? What does it do? Should I use it? When BPC is enabled under the relative colorimetric rendering intent, Adobe creates an additional color conversion that adjusts for differences in the black point. Dark colors are shifted towards lighter areas of the destination space to maintain shadow detail. However, certain colors result in chroma shifts due to this transformation. In general, the BPC option is recommended for images with high shadow content. * Credit to Jorge Uribe Understanding Black Point Compensation

25 What about printing in B&W? MK PK LK LLK C LC VM VLM Y Epson printers have additional black cartridges designed to improve the quality and neutrality of monochrome printing When using the Advanced Black & White Mode the Light Black and Light Light Black cartridges are used predominantly over the remaining colours to help produce a neutral print Monochrome printing with Colour mode Monochrome printing with Adv B&W mode

26 What about printing in B&W? Let the Printer Manage Colors Highlight Point Shift Reduce gloss differential between printed and unprinted image parts on glossy or semigloss media

31 PPi vs DPi What is PPi? Pixels per inch What is DPi? Dots per inch Newspapers often use 85dpi and the effect is clear: individual dots are visible and some detail is lost. Billboards go as low as 45dpi, but you can t tell because you re typically viewing from very far away.

32 Moiré Moiré pattern occurs when a scene or an object that is being photographed contains repetitive details (such as lines, dots, etc) that exceed the sensor resolution. As a result, the camera produces a strangelooking wavy pattern. The same principle applies when the image is printed. If the image resolution or pixels per inch does not match the printers native resolution, these lines can appear on the print. Epson recommends: 360ppi for A2 and smaller 180ppi for above A2

34 Can I print in 16bit? 8 bit 256 colour values per channel 16.7 million colours 16 bit 65,536 values 281 trillion colours
