pdf trapping

[almaink]

"in your piccys you have the trap placement as "centre""
That was just an example to show the dialog box. I mostly use Neutral Density and set my traps for .0035" and .0070" respectively.

ohh ok thanks alma

does the neutral give a less harsh trap then?

i actually dont know

I'm sure your right on that but I swear I have an Illy file that got trapped on a job last month. I'm positive there was no trapping in Illy before placing it in indesign. I'm going to go back and double check...

When you print to your rip you must select separations and Application built in Trapping .

Here is a link all about it. It's what I based my workflow on altho I altered it a bit to fit my needs.
His link tells about how to generate a trapped composite PDF from InDesign.
InDesign 2.0: Generating Composite, Trapped PDFs

Could be a tricky workflow to place PDFs in InDesign. Especially PDFs that have trapping annotations. You will see the trapping in Acrobat but place the PDF in InDesign and it's now gone. Trapping annotations are instructions that PS3 rips can understand but InDesign not being a rip, ignores them.

maybe i should have said illustrator eps - if you place an illy eps it wont get trapped - my fubar - apologies - i should be clearer!

i place a majority of my pdf's in indy colorblind - i have had no issues whatsoever with it as a way of imposing a full sheet layout (packaging layouts) to B1 and assigning trap settings - in fact its been excellent so far - but i;ll watch for the things you mention.

here's a dumm question - will that trap not show when viewing with overprint preview in indy?

if not, will the trap be honoured if you DONT assign a trap in indy then and rip the job (i have a psl3 xitron navigator)?

ya learn something new every day - except on ppf where i usually learn several new things every day!

No to both questions Beer. InDesign is generating the postscript from what it sees in the PDF, and it won't see trapping annotations. Tested it.

soooo...... if i create something in illustrator, saved as an eps, indesign wont trap for me. What if i create somthing in illustrator, add trapping, save as an eps. Will indesign honour my trapping?

Same for .ai files?
illustrator saved as pdf?

The next BIG question.... imagine a yellow background. RED 032 type and BLUE 288 type. I dont have the fonts (some idiot didn't outline it)....... so i can't access the file directly. Can i in indesign select the red to overprint but the blue not to?


Thanks for all the info so far guys, been a great help.

colorblind - thanks for explaining that - nice one

james - no - indy will not trap eps files - you have to do that in the eps files native app.

it will trap illy stuff, but be careful if copy-pasting from illy to indy - there have been instances where some attributes can get lost

the answer to the big yelow red blue question is no

you'll need the fonts, obviously, and you'll have to edit it in pitstop, pdf tuner, callas pdf whatsitcalled or neo - basically a good pdf editor - but you could draw boxes over the text and set to overprint in the background colour as a cheat....

oh - if you output film you can go with what ya got and just run some ruby over the ko areas to make an overprint...but thats oldschool....except here where i still have film and stuff....lovely.

ohhh for ctp!!!!

ahh james - just to clarify - as i'm in a mess today - seem to be all over the place - glad its friday!!

if you do traps in illy and import a eps into indy it will see and honour your traps - but careful - dont scale the image down as the trap goes with it.....

and if you trap an ai file and copy paste it, it will/should be seen by indy and honoured as well - just be very vigilant when copy pasting between indy/illy - a few have had issues here.

hope this all helps in some small way

Thanks monster!

Thats brilliant. I'll probably always do my trapping manually if possible, so that works out fine for me. It's just that odd (many) time that i don't have the font and the customer cant sort it. Indesign has become increasingly useful.

I still output film here too..... what do you mean by running ruby over it? Do you just mean block it out on the film?

Thanks for your help
