Color Correction for 3D scanner and 3D printer
Kratochvíla, Michael ; Dorazil, Jan (referee) ; Říha, Kamil (advisor)
This thesis deals with color correction of a chain that starts with the 3D Artec MHT scanner, and ends with the 3D printers (CJP – Color Jet Printing technology). In principle, it is necessary to control the color interpretation of the entire chain from the scanning of real models to the 3D print model. With color properties and their color shade, including color textures. The principle of model surface scanning using a 3D scanner is in the same principle as photo camera which scans using a conventional CMOS chip. For this reason, color palettes were scanned using the photo camera and the resulting digital data were analyzed by the Darktable software. This analysis consisted of comparing the scanned color shades of the surface with the spectrofotometer measured data. The main goal of this method was to achieve color precision in the digital data during their acquirement, adjustment and interpretation. Then the same principle was applied to the data acquired by the 3D scanner to create an ICC profile of the 3D scanner. Because the 3D printer (CJP – Color Jet Printing) uses the same principle as the 2D printer, the 2D printing device calibration principle was used again to calibrate it. There have been defined procedures that adjust the color shade to the spectrophotometrically correct shades of the resulting print on a 3D printer. Color swatches were also printed for print quality verification. It has been found that with photo camera, which was used for objective measurement in the L*a*b* coordinates of independent space, any color setting and their adjustment is very sensitive to even small imprecisions. It has been found that it is not easy to obtain accurate colors within the Detla E

Creating a 3D model and its realization on a 3D printer
LIŠKOVÁ, Markéta
The aim of this bachelor work is the creation of a 3D model and its realization. As the product of the 3D printing demonstration is chosen a bike bag for money and keys, which is placed under a seat on a seatpost. The theoretical part of the bachelor work presents a brief history about 3D printing, 3D printing technologies, editors for creating models and basic materials. The model is designed in an online editor TinkerCad. The printing is done by Fused Deposition Modeling (FDM) technology on the Original Prusa i3 MK3 printer. A part of the work is a simple handbook, which describes on a trolley coin with the JCU logo, how to create your own model and how to print it on the FDM printer.

Biography and Works of Printer and Wood-Cutter Michael Peterle (†1588)
Tvrzníková, Jana ; Voit, Petr (advisor) ; Veselá, Lenka (referee)
Thesis about life and work of a printer and a woodcutter Michael Peterle is focused mainly on his assumed woodcutting activity (he was active between years 1562-1588). It is based on following assumption: although Michael Peterle did not sign his woodcuts, he illustrated portion of his prints. His printing office produced multitude of topical compositions and some interesting illustrated books. Photodocumentation and description of woodcutting illustrations and decoration (according to Soupis tisků Michaela Peterla staršího a jeho nástupců by Pravoslav Kneidl and more recent sources) was created during writing of this thesis. Attention was also focused on context of usage of illustrations. Afterwards Illustrations and decoration of Peterle's competition in the Czech Republic and Germany were examined. Conducted research showed, that Michael Peterle was not woodcutter, but only a colorist and a printer. This thesis provides another view on printing production in the second half of the 16th century. Key words: Peterle, Michael; printer; bookprinting; woodcut; illustration; decoration

Buyer´s decision process in the printer market
Čuřínová, Simona ; Koudelka, Jan (advisor) ; Král, Ludvík (referee)
The goal of this diploma thesis is to analyze the buyer's decision process in the printer market for household. The most important of the theoretical part is the description of the whole process. The thesis is also focused on the different views on the buyer's decision process, description of factors, which influence the decision flow and on different types of the process. In the analytic part is the main attention sticked at the research of buyer's decision process in the printer (multifunction) market for households. It is based on questionnaire survey. Summing up and marketing recommendations are mentioned at the end of the thesis.
