Creating the Ticket
Life of a Job Ticket
• First for estimating purpose – by CSR or estimator / or submitted– only details that have influence on cost are
specified (no color names, no content)
• If accepted, upgraded to production ticket – by production planner or CSR– more details added (final devices, scheduling)
• Updated later with prepress details– color names, exact number of pages, content

Legend
Known at Creation
• Info available when MIS creates prod. ticket
• administrative and job info
• product nodes (part structure) and layout: binds info to sheets
• imposition, number of pages
• number of colors for each sheet side
• processes: gray boxes
Missing
• Some info is often missing when the job is created because:
• Content (PDF) arrives later
• PDF is needed to extract Spot color names
• Number of content pages for Cover often doesn't match description: 2 pages are combined in one
Introduction to Prepress
Steps in Prepress
• Creative part
• Prepress preparation (page level)– preparing content files ready to RIP
• obtaining content files
– preparing imposition
• Production prepress (sheet level)– RIP– Proofs– Plate making and Preview for ink key

Plate Making Gray box
Prepress Preparation
• Goal: no errors or interactions in prepress production part (except mapping colors)
• Steps for content (not in order)– obtaining content files (Asset Transfer)– conversion from native to standard formats– trapping– creating production quality standard formats– preflighting / fixing files– page proofs / approvals
Imposition Preparation
• Activities needed to create a description of where the pages and marks need to go on the sheet resulting in the Layout
Production prepress
• Controlled environment– nearly fixed processing times– few operator interventions/errors if well prepared– scheduling possible for plate making
• Includes Imposition Proof– often needed before starting plate making– internal or external (takes extra time) approval

In and Outs
• In– job ticket (+imposition info)– content files
• Intermediate– Proofs (hard copy or soft proof)
• Out– plates (film)– previews for ink key settings (ex PPF)
Building a Workflow
Gray Boxes
• Easy way to let MIS define what prepress should do– PrePressPreparation, ImpositionPrepreparation– PlateMaking, xxProofing
• MIS provides– input : available job info, more or less detailed– output: detailed info (sheet structure, plates,
components)
• Prepress operator (or defaults) will fill in remaining details

ImpositionPreparation Gray Box
In/Out ImpositionPreparation
• In– Stripping resources– If not available, operator intervention
• selecting a template
• recommended to give Instruction Comment
– Future
• reference to external template
• Out– Completed Layout– References to Marks
Stripping
• High-level imposition related information from MIS to Prepress
• avoids redoing imposition 3 times: – Estimating– Production planning– Prepress
• allows bi-directional communication: prepress updating imposition info
