C.Basic functions of the packaging; transporting, protecting and introducing a product. Packaging is a very important fact in today’s increasingly competitive./increased competition. For the sale of packaged products. In addition to the structural features as well as visual attention needs to be supplemented with attractive and creative ideas. Product that ready for sale, should have convincing features to the consumer. Today, packages look like each other in terms of graphic design. These similarities, complicates the selection of product by consumer. The most important impact on the consumer of packaging design; the color of the packaging. Color represent; product’s brand value, identity and reflect the character of the determined image visually. Also; color is the most important tool to separate a product and packaging from each other. In this project; consumers purchasing reactions to packagings color ,tested according to these different industries; delicatessen, cleaning product, food, etc. In this project, for achieving general results ‘’descriptive scanning model’’is used.

The digital printing system, which is increasing its effectivenesstoday, has taken great steps with technology since the first years of its existence and has started to have a voice in the sector for thelast ten years. The digital printing, which is an alternative to the offset printing system in making design a product, exhibitssignificant improvements in terms of production efficiency, cost and quality. Offset has become competitive with flexo printingwith the developing color efficiency in digital printing machines. High quality and different applications can be made with digitalprinting machines. In order to achieve this (screening) process, it is necessary to know the boundaries of the color universe that canbe seen or produced by the devices and machines used in the system. In this study, the difference between colors and colorconsistency and basic measurements such as color values, dot gain were evaluated by changing the selection of screen methodsused in digital printing. The differences caused by the screening structure variable have been shown with graphics and tables, thensuggestions have been made. It has been determined that the change in the screening structures in digital printing creates differencesin dot swelling, density and color.Publication Open Access Yenilenebilir maddelerle hazırlanan cyan renk ofset baskı mürekkebinin basılabilirlik analizleri(2022-12-01) OKTAV, MEHMET; ÖZOMAY, ZAFER; HAYTA P., OKTAV M., ÖZOMAY Z., ATEŞ DURU Ö.Ofset baskı mürekkepleri içeriğinde yer alan hammaddeler genellikle petrokimyasal maddelerdir. Mürekkep bileşeninde bağlayıcı, çözücü ve katkı maddesi olarak yer alan petrokimyasal maddelerin bazıları baskı esnasında ve sonrasında mürekkep filminden ayrılırlar. Havaya, suya ve toprağa karışabilen bu maddeler insan sağlığı ve çevre için zararlı olabilmektedir. Bu kapsamda çalışmada; iki tür ofset baskı mürekkebi hazırlanmıştır. Mürekkep 1 Aspir yağı ve Pinus pinaster (sahil çamı) reçinesi ile mürekkep 2 mineral yağ ve Pinus pinaster reçinesi kullanılarak formüle edilmiştir. Mürekkeplerin farklı tür kağıtlar üzerine ofset baskı tekniğiyle test baskıları yapılmıştır. Baskıları yapılan kağıtların baskı anı ve mürekkep kuruması sonrası renk ölçümleri yapılarak ofset baskı tekniğine uygunluğu incelenmiştir. Ayrıca piyasada kullanılan standart bir cyan renk ofset baskı mürekkebi doğal bileşenlerle hazırlanan iki mürekkeple birlikte analiz edilerek karşılaştırma yapılmıştır. Çalışmanın sonuçlarında görülmüştür ki; kuruma sonrasında Mürekkep 1 ile baskısı yapılmış olan kağıtlardan uluslararası standartlara göre en iyi sonucu veren Bristol karton olmuştur. Bristol karton ΔE=6,6136 ve densite=1,2 değerlerinde ölçülmüştür. Mat kuşe kâğıt ΔE=10,94 ve densite=1,14 değerleriyle bu mürekkeple baskı uygunluğu en düşük kağıt olmuştur. Tüm analizlerin sonucunda doğal bileşenlerin mürekkep içeriğinde kullanılabileceği fakat nihai standart üretim için bileşenlerin oranlarının değiştirilerek standart değerlerle eş değer sonuçların elde edilebileceği gözlemlenmiştir.Publication Open Access Environmentally friendly dyeing of waste cellulose fiberwith natural dye extract obtained from walnut shell(juglans regia)(2023-05-15) ÖZOMAY, MERAL; ÖZOMAY, ZAFER; Kaya S. S., Doğru D., Adeel S., Özomay M., Özomay Z.Cellulose is an important raw material in the manufacture of paper. Cellulose is formed by thefelting, fringing, swelling by absorbing water of the fibers and the combination of these fibersas a result of certain processes. Paper is also obtained by processing plant fibers. It is alsopossible to reuse the waste paper, which are completed in utilization, in paper production byrecovering the cellulose in its structure. Recycling is the process of transforming these wastepapers, which can be reused, into a second raw material by subjecting them to physical orchemical processes. In addition to being sustainable, significant savings are achieved in theamount of raw materials used in paper recycling. In addition, this saving is economicallybeneficial to production due to the high cost of raw materials.In this study, natural dye plants and natural dyeing methods were used to produce paper fromrecycled cellulose with the aim of increasing sustainability. In order to prevent the negativitiesoriginating from the increase in carbon emissions that synthetic dyes cause, it is aimed toincrease the use of natural dyeing methods in paper production. Since natural dye plants areproduced from plant itself or its waste, they do not cause environmental pollution and provideadvantages for recycling.In this study, cellulose fibers were colored with natural dyeing method using walnut shell.Thus, between the fibers, samples colored with walnut shells and samples that were notcolored were examined under two different conditions. Samples were prepared in twodifferent ponds, 5 L and 8 L, with a fixed ratio of solids. Paper sheets were formed with thesieve using the dipping method in the prepared concentration and at the same time, thetechnical properties of the samples were examined by reducing the fibers at a certain rate.Samples were measured in terms of weight, color measurement, light fastness, contact angle,surface smoothness, air permeability and compared with the data obtained.Keywords: Waste paper, Recycling, Natural dyeing, SustainabilityPublication Open Access Analytical characterization of bible and textiles artifacts from sinope balatlar church excavations for conservation purposes(2022-01-01) ÖZOMAY, MERAL; ÖZOMAY, ZAFER; Massadikova G., ÖZOMAY M., ÖZOMAY Z., Hasanova R.© 2022. This is an open-access article distributed under the terms of the Creative Commons Attribution License. Archaeological textile and paper materials shed light on cultural studies in different fields. In this study, a composite textile material and 2 printed Biblical artifacts of the 19th c., found during the excavation of the Balatlar Building Complex were investigated. The building complex, also known as the Balatlar Church or Mithridates Palace, is an imperial hamam complex belonging to the Roman Period, located in the Ada Street of Sinope province in the north of Turkey. It was found that different materials such as metal yarn, paper used under embroidery, and decorative beads used on textile material were used in the textile fragment recovered from tomb VIII of the Balatlar Building Complex. The investigation concerned the fiber types and dyestuffs for textile material, paper types and dyestuffs used for biblical artifacts by using non-destructive and microa-nalysis methods for these unique heritage objects. Attenuated total reflectance-Fourier transform infrared spectroscopy (ATR-FTIR), Optical microscope (OM), Digital Microscope (DM), Scanning Electron Microscopy with Energy Dispersive X-Ray Analysis (SEM-EDX) and High-Performance Liquid Chromatography-Diode Array Detector (HPLC-DAD) was used. It was determined that the textile find consists of two different fabrics, the main fabric, and the lining, and the dye that gives the main fabric its red color is the root dye (Rubia tinc-torum L.). Also, Alizarin and madder (Rubia tinctorum L.) was determined as a plant source. It has been estab-lished that only the pattern threads are silk threads. HPLC-DAD chromatograms has been analyzed of paper pieces of the, written and unwritten sides, paper-board and leather sides archaeological L.(Large) Bible and S. (Small) Bible books. It was concluded that natural dyestuffs were not used in the production of the paper and leather parts of the L.Bible and S.Bible books. For the written text Iron (III)-gallic acid binary complex vibration bands were detected. Documentation and research studies conducted on 2 discovered Biblical artifacts have shown that biological degradation has oc-curred on the surface of the artifact. As a result of microscopic examination, it was found that the cover part of the L.Bible was made of cardboard and there were remnants of gray side paper. Remnants of leather-pre-pared binding were found on the surface of S.Biblical artifact.Publication Open Access Effect of the Coating Formulation on the Barrier Properties and Final Appearance of Non-wettable Hybrid Paper Sheets(2024-01-01) ÖZOMAY, ZAFER; UZUN, MUHAMMET; SÖNMEZ, SİNAN; Evren G., Söz Ç. K., ÖZOMAY Z., UZUN M., SÖNMEZ S.Thin coating layers of cross-linked polydimethylsiloxane (PDMS) and inorganic particles including glass spheres (GS), colloidal and fumed silica (aero and N20), montmorillonite (MMT), and kaolin (K) were attached onto Grade 1 Whatman filter paper (WFP) substrates using the spraycoating procedure to achieve superhydrophobic hybrid paper sheets. Coating formulations were varied in terms of their PDMS molecular masses and inorganic particles to prepare different samples. The effect of PDMS molecular weight and change in inorganic particle composition on the optical properties, surface roughness, barrier properties, surface chemistry, and topography was investigated. Hybrid paper sheets with ΔE00 values lower than 1 could be achieved, the surface roughness of which could be decreased by increasing the PDMS molecular weight in the coating formulation. Scanning electron microscopy studies revealed a homogeneous coating distribution, resulting in significant improvements in both the air and water barrier properties of the hybrid paper sheets. Spectroscopic investigations revealed the presence of interactions between the coating layer and the underlying paper substrate. Moreover, the distribution behavior of the inorganic particles on the spraycoated surfaces using the proposed method was also investigated using model compounds.
