Physical inactivity, unhealthy diet, fast-paced lifestyle, as well as genetic predispositions lead to the appearance of diabetes mellitus, and with it many other complications, of which diabetic foot syndrome is very common. In order to avoid complications with the diabetic foot, one of the forms of prevention is wearing specially designed footwear that protects and reduces the pressure on the foot and thus the risk of ulcers. Insoles also play a big role in preventing complications. The paper will present a conceptual solution of a model of footwear for patients with diabetes mellitus and a prototype of an insole made of knitwear, which was previously printed with medical clay, honey and extracts of the plants Rosmarinus officinalis and Zingiber officinale. Samples of knitwear that were printed with a paste containing Rosmarinus officinalis extract showed exceptional antimicrobial activity against Staphylococcus aureus bacteria. Replaceable insoles for footwear are intended for the prevention of complications from Diabetes mellitus.

It is known that gloss has a significant impact on colour measurement. The UV varnish used for surface finishing, spot effects, as well as special effects, such as 3D effects and formation of Braille, has a pronounced gloss effect. In this work, a comparison of the spectrophotometer measurement geometry influence on the colour measurement of an unprinted PVC sample covered with UV varnish was done. UV varnish was applied successively in layers, and patches with different number of varnish layers, from 1 to 12, were formed. Two spectrophotometers with different measurement geometries were used for the measurement: Konica Minolta CM-2600d with d/8 measurement geometry, with spectral reflection included and excluded, and different measurement aperture 3 and 8 mm, and X-Rite eXact with 45/0 measurement geometry. By comparing the measurements, it was estab-lished that there is a significant difference in the measured values between different measuring device geometries on the given samples, and that the number of UV varnish layers has a significant influence on this differenc

Kullanim sirasinda farkli islemler baskili tekstil urunlerini etkiler ve bu islemlerden en yaygin olanlarindan biri yikama islemidir. Yikama islemi tekstil yapisinin ve tekstil liflerinin modifikasyonuna neden olur. Bu arastirmanin amaci, elyaf baskili pamuklu orme tekstil malzemelerinin baski kalitesi parametrelerine yikama isleminin, yikama islem sicakliginin ve baskili malzemenin ozelliklerinin etkilerini belirlemektir. Renk indeksi uzerinden spektrofotometrik analiz ve makro daginiklik analizi kullanilarak etkiler belirlenecektir. Arastirma sonuclari, yikama islemlerinin sayisinin arttirilmasinin ve ayni zamanda yikama sicakliginin arttirilmasinin, yikanmis ve yikanmamis numuneler arasindaki renk farkinin artmasina neden oldugunu gostermektedir. Ayni zamanda, substrat ozelliklerin renk farkliliklari uzerinde buyuk etkisi oldugunu da gosterir. Bunun yaninda, yikama islemi ayni zamanda baski kalitesinde gozle gorulur degisikliklere neden olur ki bu yine substrat ozelliklerine baglidir.

Tekstilni materijali tokom upotrebe bivaju izloženi različitim spoljašnjim uticajima. Jedan od češćih uticaja kojem su ovi materijali izloženi je toplotno dejstvo. Toplota na tekstilnom materijalu izaziva promjenu strukturnih karakteristika vlakana, čime dolazi i do promjene reprodukovanih otisaka. Cilj ovog rada je da ispita uticaj toplotnog dejstva na kvalitet sito štampanih tekstilnih materijala. Istraživanje je obuhvatilo i analizu zavisnosti kvaliteta štampe od karakteristika štampane podloge, te karakteristika korištene štamparske forme. Eksperimentalni rezultati analiziranih otisaka prije i nakon toplotnog dejstva, dobijeni spektrofotometrijskom analizom reprodukovanih boja kao i digitalnom obradom slike, ukazuju da toplotno dejstvo utiče na kvalitet reprodukovanih otisaka. Rezultati istraživanja su potvrdili i zavisnost kvaliteta reprodukcije od karakteristika materijala na kojem se vrši proces štampe, kao i od karakteristika štamparske forme pomoću koje se vrši proces štampe.

Digital printing has matured and it is now present in daily production. This is true for both the large format inkjet printing and digital commercial printing (with toner based and increasingly with ink jet technique). In the graphic arts industry in particular the latter use case shows tremendous growth figures where small and medium run lengths are taken over increasingly from the offset market (Kraushaar, 2010). As digital printing industry grows every day a lot of work has been done in improving and developing new technologies and products. This increased growth demands higher level of quality assessment in order to be able to compare different products and technologies and evaluate them (Pedersen et al., 2011). Most production digital printing processes depend on the use of certified paper to perform to their best capacity. Any adjustments that need to be made to the actual press require the intervention of technical support personnel other than the press operator (Chung & Rees, 2007). Print quality is very important in each printing technology, and also for digital printing (Rilovski et al., 2012). A common way for analyzing the print quality is to quantitatively assess image color and tone value reproduction using corresponding measuring device. This way of analyzing print quality is easy, since tone and color are easily perceptible, but they are not enough for determining print quality (Dhopade, 2009; Kiurski & Oros, 2012). Several experiments proved that print quality is not a monotonic function of hue, saturation and brightness (Fedorovskaya, Ridder & Blommaert, 1997; Pedersen et al., 2009). Quantitative print quality assessment depends on a number of quality attributes (Pedersen et al., 2011; Rilovski et al., 2012). There are several of them such as contrast, sharpness, macro-uniformity, etc., which are not associated with tone and color but have considerable influence on print quality. They are directly connected with line and dot quality, which are structural elements of any image (Dhopade, 2009). So far many researches have been done that confirmed the importance of different quality attributes, but there is no overall agreement which of them are most important (Pedersen et al., 2011; Rilovski et al., 2012). One of the reason is multidimensionality and complexity of image quality (Pedersen et al., 2011).
