How does tFLOW handle adding bleed to files?
 
If your preflight or finishing script includes options to add bleed to your files, beside choosing to enable or disable this option, you get the choice of how this bleed is added, and how much bleed to add. The amount of bleed you add and how the file is setup has a direct effect on whether tFLOW adds bleed or not.
 
See the tables below:
 
ADD
BLEED?
BLEED EXISTS
IN FILE
BLEED NOT
IN FILE
YES
Bleed is added by tFLOW when bleed exists in the file if tFLOW bleed > art file bleed
Bleed is added by tFLOW
NO
No bleed is added by tFLOW when "add bleed" = false.
No bleed is added by tFLOW when "add bleed" = false.
 
Generally, if a file comes with bleed into tFLOW, and add bleed is turned on, it doesn't add bleed to the file.
But it's not entirely cut & dry when it comes to this combination. There is a "check" happening behind the scenes that looks at how much bleed is in the file. See this 2nd table:
 
IF
Bleed in tFLOW > File Bleed
Bleed in tFLOW < File Bleed
THEN
Bleed is added to the file
No bleed is added to the file
 
So if the file arrives with 1" bleed all around, and you add 1.25" bleed in tFLOW's preflight script, then tFLOW will expand the bleed, from the trimbox, out to the distance you have specified, with the method you have chosen (repeat last pixel or mirror as image) in this example being 1.25" out. It overrides the bleed that the file came with and uses the larger tFLOW value & method instead.
 
Important:
Bleed can be added either via the Preflight script or the Finishing script. Be sure to only add bleed using one or the other, but not both as this may cause issues with the file when it's sent to production.
