AVOIDING MOIRÉ PATTERNS
mon mistake with tones is that they create these unsightly patterns in them in the
ic. These are called moiré patterns. What are they, and where did e from?
Simple: moiré patterns are like optical illusions and are created when the dots of tones are
resized or overlapped improperly. It’s important to tone on an original, pressed fi le
and know what the print size and resolution will be, whether it’s the native Manga Studio fi le
format, a native Photoshop PSD fi le, or a TIFF fi le. The resolution needs to be around 600
DPI (Dots Per Inch) to 1200 DPI depending on the printer. Toning on a high-res fi le means
that when the page appears in the print manga, the toning appears exactly how you intended
and not with weird patterns in it.
Preventing moiré is easy in Manga Studio, but there are times where you need to be cautious.
When layering tones that are in black and white, the tones must be the same L, or they will
cause moiré patterns. Watch the angle of the overlapping tones as well; binations
of different angles could cause moiré as well.
Never save a drawing as a JPG and then attempt to tone on it. The only time to save
separately in the JPG format at all is when the page pletely done, and the only reason
to save in this format is to do a ic or for other use such as on MySpace or an
online portfolio. When resizing a black and white toned image for the web, moiré can occur
as you try to shrink it to a size less than printing size. This can be resolved by reducing it to
75% repeatedly until you get to an appropriate web size.

Also, never save a drawing in a resolution below 600 DPI and attempt to tone on it, as
again this will create the moiré patterns in the actual work. Tone as high-res as you can or as
high-res as the DPI output of the printer. Toning a high-res document requires at least
gigabytes of cach
