Lectures Week 1-6 Notes

Week 2 Preflighting I
Introduction & Manual
* Preflighting is not always done by one person.
* The client can fix it as well

* Fonts are still the biggest problems regarding pre-flight because of the different types of fonts there are. DO NOT USE CITY FONTS. Manual & Software Assisted
* You should change the size / crop the image in Photoshop, so that it’s size-as in inDesign. * Do not use .gif images, and you can sort of get away with .jpg but it is not advised. * Link every image, and make sure it’s updated.

* For vectors, you should stick with .ai, .pdf, .eps.
* Less editable

* Approximately 5 common styles of imposition:
* Sheetwise / Sheetwork (SW)
* Perfecting
* Work & Turn
* Work & Tumble/Flop
* Flatwork
* Form: one side of a signature
* Page/Folio: one page – single side of a page or paper. * Sheet: One piece of substrate
* 1-up/out: One set of sheet makes one final product.
* Tumble flips the sheet over.
* Must cut paper before printing for perfect size. Make sure the length of the sheet is the same on all sheets to ensure proper registration. * Flatwork is a job that does not require any sheet work. It is usually a single sided sheet. Imposition Styles
