VP-TXT 2 Setting of character vectorization
Detail To set vector conversion processing for text on scalable PDF.
In the vector conversion processing, a binary image outline is extracted in the field which is
recognized as text, and is converted into vector data.
In regular vector conversion, function approximation is not used for small text because the image
quality is not changed.
When the value is changed, function approximation processing is executed for small text, which
realizes smooth text although the image quality is changed.
Change this value when you want to prioritize smoothness in small text.
Use Case Upon user's request
Adj/Set/Operate Method 1) Enter the setting value, and then press OK key.
2) Turn OFF/ON the main power switch.
Display/Adj/Set Range 0 to 99
Default Value 1
C-PDL-T 2 Setting of PDL gradation reference
Detail To set whether gradation or density to be prioritized as the gradation reference for PDL.
With priority on gradation (% of halftone dots), gradation is matched with original on the shadow
area although the maximum density decreases. With priority on density, density is always matched
with original.
Use Case
Upon user's request
Adj/Set/Operate Method
Enter the setting value, and then press OK key.
Display/Adj/Set Range
0 to 1
0: Priority on gradation (% of halftone dots), 1: Priority on density
Default Value
0
Supplement/Memo
Abbreviation of CAL_PDL_Target
C-S-P-D 2 High dens end edge crrct: PDL dens prrty
Detail To set ON/OFF of high density trailing edge correction function at PDL.
By selecting CAL (priority on density) in C-PDL-T, high density trailing edge correction function is
ON in normal operation; however, set OFF as needed.
Use Case ON: When reducing jagged line and jagged outline of text
OFF: When matching density with original on high density area, or when prioritizing density and
gradation
Adj/Set/Operate Method Enter the setting value, and then press OK key.
Display/Adj/Set Range 0 to 1
0: OFF, 1: ON
Default Value 1

Supplement/Memo Abbreviation of CAL_Shadow_PDL_Density
C-S-C-D 2 High density end edge crrct ON/OFF: copy
Detail To set ON/OFF of high density trailing edge correction function at copy.
With CAL of COPY, high density trailing edge correction function is ON in normal operation;
however, set OFF as needed.
Use Case
ON: When reducing jagged line and jagged outline of text
OFF: When matching density with original on high density area, or when prioritizing density and
gradation
Adj/Set/Operate Method
Enter the setting value, and then press OK key.
Display/Adj/Set Range
0 to 1
0: OFF, 1: ON
Default Value
1
Supplement/Memo Abbreviation of CAL_Shadow_COPY_Density. When adjusting the input signal 255 to low in the
case that the density of solid area is too high, jaggy (jagged effect of halftone) may occur to text,
etc. By entering the input signal 255 as solid, occurrence of jaggy can be prevented.
