DRM = The Distance to Registration Mark is the distance from the leading edge of the
printable area to the beginning of the registration mark.
SBL = The Space Between Labels is the non-printable distance between the media,
typically found on die-cut labels. If the media contains space between the actual
printable portions of the media being used, this would be the SBL parameter.
Please note that this does not reflect a blowhole or black line height, as these
registration marks are typically positioned within the printable area. When die-cut
media is used, this value is also used in the GAP header parameter.
Calculation Examples:
Die-cut Media:
A 203 DPI printer is being used with 3" x 1" media containing a .125" die-cut gap. The SPG
would be calculated as follows:
SPG = (D2G + LSY - DRM) mod (LSY + SBL)
SPG = (264 + 203 - 203) mod (203 + 25)
SPG = 264 mod 228
SPG = 36
D2G (264) =
LSY (203) =
SBL (25) =
DRM (203) =
The SPG may also be determined by adding a line at dot row #1 using Line Draw (See
Section 4.7) and adjusting the SPG number up and down to get desirable registration with
the line printing at the bottom edge of the media.
4.4.10 OFX (Offset X Direction)
HFM, LSX, LSY, WEB, GAP, DPS, LCB, AGD, SPG,
This parameter is used to move or offset all format fields in the X direction without altering
the format fields coordinates themselves.
4.4.11 OFY (Offset Y Direction)
HFM, LSX, LSY, WEB, GAP, DPS, LCB, AGD, SPG, OFX,
This parameter is used to move or offset all format fields in the Y direction without altering
the format fields coordinates themselves.

The Dot to Gap distance for the transmissive sensor (Table 4-2).
The height of the printable area; 1" x 203 DPI = 203 dots.
The Space Between Labels, or die-cut GAP in this case;
.125" x 203 DPI = 25 dots.
The Distance to Registration Mark is from the leading edge of
the printable area to the next registration mark;
1" x 203 DPI = 203 dots.
