B.1.2.9 Requirements for Transparency Rate of Die-Cut Label Paper
If transparency (without black marks) label is used, use a label that meets the following
requirements so that the printer can recognize the label position:
Note:
❏
Transparency rates are measured by the Macbeth TD-904 (with a filter for infrared) photometer. The
transparency rates are calculated as follows:
Use
Density = Log
Then,
Transparency rate (%) = (Amount of transparency / Amount of irradiation)
B.1.2.10 Requirements for Black Mark Position for Die-Cut Label Paper
If die-cut label with black marks is used, there are two reflective rate requirements, depending
on the size and position of black marks. Be sure to use label paper that meets either black mark
position requirement I or II as follows:
B.1.2.11 Requirements for Black Mark Position I
The black mark positions on the paper to be manufactured must meet the requirements in the

combinations shown in the table below (the reflective rate is measured using the back of the
paper, the non-printing side):
Reflecting rate for black mark portion 1
Reflecting rate for label portion 2
