Goal(s)

Learning outcomes :

  • Master the operation of the offset process and in particular the interactions between the various phenomena involved;
  • Know the materials and consumables (fountain solution, plates, blankets) associated with this process (excluding inks);
  • Know the characteristics and operation of the different types of offset presses (sheet-fed, web-fed);
  • Recognize printing defects related to these presses and develop the method for diagnosing them (observation, use of tools, interpretation);
  • Optimize the use of the offset process.

A-Principles of the offset lithographic process : dampening, inking, transfer.
B-Materials and consumables used : dampening solution, plates, blankets
C-Offset lithographic presses
D-Characteristic defects of offset lithographic presses.

Three practical sessions are carried out on the SHeetfed Offset Training Simulator (SHOTS) and allow to learn how to diagnose offset printing problems.
The first one is intended to learn the operation of the simulator and the diagnosis methodology.
The next two sessions place the students in production situations where problems gradually appear. The second session can also be supervised (to avoid risks of blocking in a given situation). The third session is carried out independently.
Two modes of operation are possible:
1. The students install a laptop in a room with a video projector and a network connection (the software is accessible via the network).
2. The session is done remotely, by videoconference.
The availability of the software (and in particular the number of possible simultaneous connections) or the constraints of the schedule may modify this organization.
A one-hour plenary session allows for an assessment of the difficulties encountered during the work carried out independently and of the knowledge acquired through this approach.

Depending on the health constraints in effect, the sessions may be held at a distance.

Prerequisites

  • Basics of printed communication engineering (densitometry).
  • Understanding English (course taught in English).

Accessibility for people with disabilities : please contact us for further information

Test

  • Specific credits: this course brings 1.5 ECTS to students in Print sciences processes & materials

The course is taught in English.

A joint evaluation is proposed for the offset printing, flexography and digital processes courses.
Can be made up in case of a justified absence.

In the event of a health constraint, the exam will take place remotely, in the form of an online multiple choice questionnaire.

Grading of the practical work : the methodology used by each group of students to solve problems during their self training on the simulator is taken into account.
The exercises on the simulator will be corrected in a plenary session.

The practical work on the simulator can be made up in case of a justified absence if access to the simulator on the "cloud" remains possible.

La note de TP tient compte de la méthode de diagnostic employée, de l'utilisation de l'aide au diagnostic, du nombre de problèmes résolus, et d'éventuels problèmes rencontrés par le logiciel.

The grade of the practical work takes into account the diagnosis method used, the use of the software help, the number of problems solved and possible software bugs.

La note du DS est une évaluation commune aux trois cours : Flexographie, offset, procédés numériques.

Environmental security

Les consignes relatives à la sécurité et à l'environnement sont évoquées en tant que de besoin. Les enseignements ont lieu dans des salles de cours ou des salles informatiques.
Penser à éteindre ordinateurs et lumières en quittant la salle.
Safety and environmental constraints are mentioned when appropriate. Teaching takes place in classrooms.
Turn off computers and lights when leaving the classroom or computer room.

Si travail autour d'une presse industrielle: respect des consignes de sécurité détaillées par l'enseignant avant les travaux.
Cheveux longs attachés autour des machines, pas de foulard, pas d'habits flottants.
Les éventuels effluents sont collectés pour être évacués par des prestataires spécialisés / interdiction d'évacuer les effluents dans les réseaux communs.

If work around an industrial press : respect the safety rules described by the teacher : no "floating" clothes, attach long hair, etc.
If effluents are generated, they are to be collected by specialized companies and shoould not be thrown into the sink or sewage.
