More on Colour

So far the test colours on the Epson Stylus Photo R2880 are looking very impressive, so let's take a closer look.

Black & Browns	Reds
Yellow & Green	Blues

As mentioned on the previous page, the print is slightly darker than the original digital file. This has had the effect of over saturating the colours, which I don't personally mind. The new colours claim to produce smoother gradients from shadow to highlights and an increased colour gamut. Generally these sort of claims are true, but often you will be hard pushed to see any difference in the print . The R2880 has produced excellent prints, although when I lay the test prints out side by side with other prints and look at them with my eye balls I can't help thinking that the improvement is only minor. Perhaps using an instrument to measure the values would give me an accurate confirmation that this printer has indeed improved the colours, but as a photographer I prefer to rely on my eyes.

Just for those who want to see what improvements EPSON has made with the colour Gamut New UltraChrome ink Gamut is increased in the purple and blue area

LUT

Epson's New LUT technology automatically generates a Look Up Table (LUT) for specific ink technology in use, this converts the RGB signal into the correct values for each ink thereby optimising the Gradation (smoothness), Graininess (print dots), Colour Gamut ( colour you can see) and Colour inconstancy (viewing prints under different lighting conditions)

Converting RGB to CMYK or PB,LB,LLB,C,,LC,VM,VLM,,Y
Poor Gradation of colours	Good Gradation of colours
LUT for poor Gradation	LUT for good Gradation
LUT with poor grain characteristics	LUT with good grain characteristics

So you can see from the charts and eye ball samples above that there is an improvement in the technology. Maybe I am a cynic, but I have to see for myself if the improvements can be seen by a user. Let's take a look.
