Preﬂighting - File Construction for Print
Preparing Files for Print!
-Mistakes cost money - further down the line you make mistake (or catch mistake), higher cost of mistake!
Top 10 File Prep Problems!
•Missing fonts = common problem when clients send ﬁles!
•In application ﬁle (eg. InDesign), package your work so that fonts are included when submitted to prepress department!
•Less of an issue when working with PDF, as fonts are embedded/subset in ﬁle!
•Brackets around if font is missing!
•Pink highlight around text if font is missing!
•Beware of GhostFont, where there’s text box but not text!
•Comes from not packaging ﬁles correctly!
•Can open old ﬁles on new program, but not new ﬁles on old program!
•Incomplete ﬁles from customer with missing pages/sections!
•Ensure that ﬁle will open correctly in application you’re using!
•Check Info Panel in InDesign!
-Image colours issue if it’s still in RGB mode when imported into InDesign for print!
-Ensure B&W images are saved greyscale, not CMYK/RGB!
•Ensure spot colours aren’t used if image will be printed 4-colour process: convert if needed!
-Spot colour = speciﬁc colour not in CMYK (gold, silver, etc)!
-Spot colours require additional plate & expensive!
•Ensure type isn’t 4-process black!
•Make sure all colours used are saved CMYK swatches!
•1 page items = turn off facing pages!
-Final size of printed piece (live area)!
-Printed elements that extend past trim as outer safety for cutting!
-Industry standard = 0.125 inches for offset printing (different for other processes)!
-“White Space” inside live area used for aesthetic reasons and/or as inner safety for important elements!
•Lower # of ppi = looks pixelated!
•High # of ppi = slows down computer & printer!
•Good pip = double lpi!
•Should be TIFF!
•No GIF/JPEG for printing because compression is lossy (vs lossless TIFF)!
•If you open-edit-close JPEG many times, it will make photo look like crap!
•If link to hi-res image is broken/modiﬁed, image must be re-established to print properly!
•It will either print low-res version of image ﬁle or won’t print at all!
•3 rule: Don’t MOVE, RENAME, or DELETE photos once placed in InDesign!!
•Publishing = InDesign!
•Vector = Illustrator!
•Photo = Photoshop!
•Saving word document into PDF = NO!
•Lets press operator see what designer wants!
•Like a contract!
•Press operator will not print before proof!!
•Spelling & Grammar!
-Same element throughout the ﬁle!
-Making sure page order is right!
•Learn these top 10 mistakes & DON’T MAKE SAME MISTAKES!!
•File construction is detail-oriented, but doesn’t mean it’s overly complex/difﬁcult to grasp!
•Use preﬂight checklist to ensure ﬁles are ready for print before submitting
