- Abstract
Appropriate labeling and flexible packaging plays an important role on the today`s demands. There is diverse possibilities especially related to polymeric materials. Flexible packaging means to consider options such as OPP (Oriented Polypropylene), PVC (Polyvinyl Chloride), OPS (Oriented Polystyrene), PET (Polyethylene Terephthalate) or all kind of self-adhensive paper and foil types. Special highlight are the "Shrink Sleeve" labels that meet the most demanding market challenges. Its capabilities are beneficial. Laminated packaging materials are functional. Both constitute protection and packaging capacity. Coefficient of friction is the value that serves to meet the standard of how the flexible packaging material will glide and move on the packaging machine. This research is focused on the optimum quality of the packaging production process to meet all the preconditions for implementation of the semifinished product packaging and to avoid difficulties and possible stoppages on the packaging machine itself.

- Abstract
There are several methods for the measurement compressive strength of linerboard and fluting medium paper. The results of different method can vary up to 30% and more for same material sample and the biggest challenge is to determine compressive strength uninfected by other properties. It still isn’t specified which method is technically more correct. The Short-Span Compressive Test (SCT) method is assumed to be more accurate. However, the Ring Crush Test (RCT) method is still widely use despite that it is established it is affected by buckling load of test specimen. In this study these two different methods were performed to measure the compressive strength of corrugated board’s components. The results were implemented in Maltenfort equation for prediction of board compressive strength. The accuracy of methods was evaluated by comparing predicted compressive strength with measured board edgewise compressive strength (ECT). The result confirmed that SCT method is more successful for predicting compressive strength of corrugated board and therefor, more accurate.

- Abstract
Test charts are a tool commonly used for the evaluation of colour reproduction system accuracy. They may vary in size and choice of values tested. Within statistical quality control, the importance of random sampling is very often stipulated. However, in the context of the evaluation of colour reproduction system accuracy, samples are very small with respect to the number of possible device inputs. It is therefore very common that practically usable test charts of sizes of a few hundred patches underestimate the maximum error. Including a larger number of critical values such as those at the gamut boundary increases the probability of estimating the maximum error more accurately. However, the sample is no more random and the inclusion of a larger number of critical values inevitably increases the central tendency measures. The aim of this research is to improve the maximum error estimate, while retaining the central tendency estimates within the range of statistically insignificant differences. This is achieved by adding critical values to the chart of sufficient number of patches.

- Abstract
The most important criterion for pronouncing a certain production process to be successful is that it produces products of the desired quality level. Attaining quality is the aim of every production process. Achieving superior quality is possible by ensuring that a production process is being conducted under the best possible conditions. Another important step toward quality is employee education. Ensuring the best production conditions and the best education of employees requires enormous investments and does not lead toward optimization because the costs of quality become too high. Printed material has the aim of meeting certain requirements for quality in order to successfully transfer the message to consumers on the competitive market. In the production process of this dynamic, every fault results with delays in delivery and quality reduction. This paper investigates current approach to quality in the graphic arts industry, and elaborates the model of applying knowledge from the field of quality management to the printing industry., Najvažniji kriterij proglašavanja nekog proizvodnog procesa uspješnim je sposobnost tog procesa da proizvede proizvod tražene kvalitete. Postizanje kvalitete je cilj svakog proizvodnog procesa. Superiornu kvalitetu moguće je postići osiguranjem najboljih mogućih uvjeta u kojima se odvija poizvodni proces. Druga važna aktivnost je edukacija kadrova. Osiguranje najboljih mogućih uvjeta i najbolje edukacije kadrova zahtijevaju velika ulaganja pa troškovi kvalitete postaju previsoki. Takav pristup, ako i jest praktično izvediv, ne vodi optimizaciji. Tiskani materijal mora udovoljiti određenim zahtjevima za kvalitetom kako bi na konkurentskom tržištu uspješno prenio poruku potencijalnom kupcu. U tako dinamičnoj proizvodnji kao što je grafička, svaka greška uzrokuje kašnjenje i pad kvalitete. U ovom članku izneseni su rezultati istraživanja trenutačnog stanja u grafičkoj industriji i prijedlog modela implementacije znanja s područja kvalitete u grafičku proizvodnju.

- Abstract
S obzirom na sve veću konkurenciju koja se pojavljuje na svjetskom, ali i hrvatskom tržištu, organizacije će morati pristupiti sistematičnom i profesionalnom organiziranju proizvodnje i usluga. Iz tih razloga pojavljuje se cijeli niz metoda, koncepata i standarda koji nastoje pomoći organizacijama u sustavu upravljanja. U organizacijama koje nastoje obuhvatiti tri bitna elementa za upravljanje uvode se tzv. integrirani sustavi upravljanja: ISO 9001:2000 – Sustav upravljanja kvalitetom; ISO 14001:2004 – Sustav upravljanja zaštitom okoliša i OHSAS 18001 – Sustav upravljanja zdravljem i sigurnošću na radu., In the face of mounting competition on the world and Croatian markest, organizations will have to embark on a systematic and professional reorganization of their production and services. For that reason, a wide range of methods, concepts and standards have emerged in an attempt to assist organizations with their management systems. In organizations that are trying to cover three important elements of management, the so called integrated management systems are being introduced: ISO 9001:2000 – quality management system, ISO 14001:2004 - environmental management system and OHSAS 18001 Occupational health and safety management system. This paper shows the main features of integrated management systems, areas which all management systems have in common, as well as differences among them. It describes the state of management systems in Croatian companies, in particular those related to graphic arts industry.
