What is 50% Screening

[Golestan]

Hi,
Can someone explain what is the % screening options that are on the plotter selection page. There are 25%, 50 %, etc... values. What does it mean and what is the effect on the plotted drawing.
Thanks,

Hi,

did you test it?
It's the intensity of the plotted color.

Screening is kinda making lines lighter - it uses less ink Me personally don't use this option - I prefer plotting with little value of lineweight. Something like 0.05 for example

@notman,

how would you screen a solid hatch...?
I think with screening you would have more "colors" for the plot.

Screening reduces the 'saturation' of the color. For inkjet plotters/printers, this is fewer 'dots per unit area', so the color is 'lighter'.

We use this to get 'faint' colors. For example, color 3 with a 10% screening gets you a faint 'lime green' useful for solid hatching/highlighting an area inside a REVCLOUD.

The hatch will still completely cover whatever may be 'behind' it, so make sure that the highlight hatching layer(s) are at the 'back' of the objects in your drawing.

At the land surveying company i'm with, we hatch the roads, using 15% screening (all black/white plottings), this greates a grey road, looks nice.
