What is 50% Screening

What is 50% Screening

What is 50% Screening

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.

RE: What is 50% Screening

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 :)

RE: What is 50% Screening


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

RE: What is 50% Screening

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.

RE: What is 50% Screening

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.
