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!
-Incomplete/Corrupt Files!
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!
-Document Construction!
1 page items = turn off facing pages!
Trim (Black)!
-Final size of printed piece (live area)!
Bleed (Red)!
-Printed elements that extend past trim as outer safety for cutting!
-Industry standard = 0.125 inches for offset printing (different for other processes)!
Margins (Purple)!
-“White Space” inside live area used for aesthetic reasons and/or as inner safety for important elements!
-Resolution/Image Quality!
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!
-Missing Images!
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!!
-Wrong Applications!
Publishing = InDesign!
Vector = Illustrator!
Photo = Photoshop!
Saving word document into PDF = NO!
-No Proofs!
Lets press operator see what designer wants!
Like a contract!
Press operator will not print before proof!!
-Other Considerations!
Spelling & Grammar!
Layout consistency!
-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
