Print Quality

 

Description

 

 

 

Too dark

 

Labels that are too dark are fairly obvious. They may be

 

 

readable but not “in-spec.”

 

 

• The normal bar code bars increase in size.

 

 

• The openings in small alphanumeric characters may fill in

 

 

with ink.

 

 

• Rotated bar code bars and spaces run together.

 

 

 

Slightly dark

 

Slightly dark labels are not as obvious.

 

 

• The normal bar code will be “in-spec.”

 

 

• Small character alpha numerics will be bold and could be

 

 

slightly filled in.

 

 

• The rotated bar code spaces are small when compared to

 

 

the “in-spec” code, possibly making the code unreadable.
