Description
The writer is describing how to use a marker pen. First, shake the marker well to mix the paint. Then, depress the nib a few times to start the flow of paint. The valve remains open and releases paint the entire time the nib is depressed, so if the pen is held down for a long period, a large amount of paint is released. When you see paint appear on the nib, wait until the paint has stopped travelling down the nib before depressing the nib again. When the nib is adequately saturated, test the marker by applying it to artwork. If the marker needs to be re-pumped, do so, but never directly on the artwork.
Shake well before use to ensure paint is thoroughly mixed. Depress
nib a few times to start paint flow. The valve remains open and
releases paint the entire time the nib is depressed, so if held
down for a long period, a large amount of paint is released. When
you see paint appear on the nib pause for a moment. Wait until
paint has stopped travelling down the nib before depressing the nib
again. When the nib is adequately saturated, test, then apply.
Re-pump as necessary but never directly on artwork to avoid paint
splodges. It can take a while for paint to start flowing on initial
activation. This will not be experienced on subsequent use.
