The document challenges common misconceptions about image resolution, stating that quality is not solely determined by dpi. It explains the differences between RGB and CMYK color spaces, as well as the distinctions between spot and process colors in printing. Additionally, it highlights that using fewer colors can be more cost-effective, while spot colors provide a wider range of vibrant hues.

1. THINK AGAIN!

2. Do you think that...
• ...resolution has something to do with the
quality of a picture?
• ...300dpi is high resolution?
• ...Pantone spot colours are good in order to
avoid colour mismatch?

4. Which image
looks better?
300dpi 100dpi
2000x1000 pixels or 2000x1000 pixels

5. THE SAME!

16.93cm x 8.46cm 50.79cm x 25.39cm
Depends on how far they are...

8. This is RGB

9. This is CMYK

10. How similar
can they be?
DPI = Spatial dot density
Pixel per inch = Pixel resolution

11. CMYK
Print color space is separated in 4 different plates (films).
Each plate has a different angle.
50% Cyan at 75º, 20% Magenta at 15º,
15% Yellow at 0º, 5% Black at 45º

BUSTED!

13. Pantone

14. Process vs Spot
From Pantone website: There are two different ways
color can be applied to paper in color printing: spot color and
process color. Spot color is a method of applying a premixed
color of ink directly to the page. Process color applies four or
more standard ink colors (the basic four are cyan, magenta,
yellow and black) in very fine screens so that many thousands of
colors are created. Spot color is usually used when a few exact
colors are needed. Process color is more useful for printing
photographs, paintings and very complex colored images.

15. Process vs Spot
From Pantone website: The cost of printing color
documents is related to the number of ink colors used. As
process color requires four or more inks,
spot color can be cheaper if you use fewer
than four colors. Spot color also has the advantage of
printing a wider range of clean, bright colors.
