Khadi fabric is the textile glummer of India and has been started to use in India from at least ten decades ago (from 1920s). Normally it consist of cotton, wool, silk like natural fibre etc. and the concern fabric is made by hand made (by charka spinning technology) yarn and in the traditional handloom process. Normally, different kind of natural dyes (vegetable based, wastage material based, tannin based colour) and the eco-friendly synthetic dyes are used for the coloration of the khadi textile. In addition some traditional printing techniques like hand screen printing, block printing is used for the special effect on the khadi textile. Concerning the value addition, only stiff khadi fabric is marketed which is made by adding starch. However, some special low cost other value addition of the khadi fabric will make it more acceptable to the consumers of the India and also in the other countries. In this respect, bioactive based finish and the mosquito repellent khadi textile is very much important. This kind of functionality will make the fabric hygienic in terms of attack by deadly mosquitoes and also some harmful microorganisms. Apart from it, if it is possible to make UV protective and the fire retardant khadi textile, it will increase its popularity and also gain the socio economic importancy to the consumers and the handloom weavers of India and the other subcontinental countries.

Antioxidants are essential in regulating various physiological functions and oxidative deterioration. Over the past decades, many researchers have paid attention to antioxidants and studied the screening of antioxidants from natural products and their utilization for treatments in diverse pathological conditions. Nowadays, as printing technology progresses, its influence in the field of biomedicine is growing significantly. The printing technology has many advantages. Especially, the capability of designing sophisticated platforms is useful to detect antioxidants in various samples. The high flexibility of 3D printing technology is advantageous to create geometries for customized patient treatment. Recently, there has been increasing use of antioxidant materials for this purpose. This review provides a comprehensive overview of recent advances in printing technology-based assays to detect antioxidants and 3D printing-based antioxidant therapy in the field of tissue engineering. This review is divided into two sections. The first section highlights colorimetric assays using the inkjet-printing methods and electrochemical assays using screen-printing techniques for the determination of antioxidants. Alternative screen-printing techniques, such as xurography, roller-pen writing, stamp contact printing, and laser-scribing, are described. The second section summarizes the recent literature that reports antioxidant-based therapy using 3D printing in skin therapeutics, tissue mimetic 3D cultures, and bone tissue engineering.

Photovoltaic generation of electric power requires substantial reduction of costs to tap significant markets. A major cost element in the technology of solar cell fabrication for space application is formation of electrical contacts by evaporation of metals through shadow masks. Application of conductive ink pastes by screen printing provides several mechanisms for cost reduction. Screen printing techniques have been developed for fabrication of miniature electronic circuits on ceramic substrates. The process is readily automatable, and equipment with high throughput rates is available. Thus, screen printing results in reduced investment, tooling and labor costs. Silver is required for the front metallization grid, and additional savings result from application of metal only where needed. Substitution of aluminum for silver at the back contact provides further material cost savings. Metallization costs by this method are projected to be less than .05 dollar (1975) per watt as compared to about 16.00 dollars per watt by evaporation techniques.

The active use of screen printing techniques by industry sectors encourages this technique to be developed both in the use of tools or materials. It is undeniable that the use of screen printing techniques or so-called commercial screen printing makes this technique can be studied not only in formal educational institutions but also non-formal. The emerging of screen printing practitioners made this technique development specifically according to their individual needs. One of Commodification of screen printing techniques in the community is in dukuh Krangkungan, di Desa Pandes, Kecamatan Wedi, Kabupaten Klaten, Central Java. Characteristics that developed in Wedi researched using field methods of observation, documentation and interviews. Paguyuban as a place to communicate and socialize have a role to screen printing technique that exist in Wedi. The spirit of togetherness that is built in Paguyuban Kampung Sablon not only in the stage of running a business but also on various aspects besifat technically one of them is to divide the screen printing ability. Paguyuban also as a forum to exchange information about the technical, tools and materials. Paguyuban also encourages employees who have working experience as a screen printing and has mastered the technical screen printing to open screen printing services themselves. Seen from the number of members of the community that has grown from 9 at the beginning of established now become 15 units of screen printing. The screen printing unit developed will be able to survive one of them with improved quality, work ability and efficiency. Key word: Screen Printing, Commodification, Sablon  Penggunaan secara aktif teknik cetak saring oleh sektor industri mendorong teknik ini terus dikembangkan baik dalam penggunaan alat atau bahan. Tidak dapat dipungkiri penggunaan teknik cetak saring atau yang biasa disebut sablon secara komersial membuat teknik ini dapat dipelajari tidak hanya di lembaga pendidikan formal tapi juga non formal. Praktisi sablon yang akhirnya bermunculan juga mengembangkan teknik ini lebih spesifik sesuai dengan kebutuhan masing-masing. Komodifikasi teknik cetak saring di masyarakat salah satunya di dukuh Krangkungan, di Desa Pandes, Kecamatan Wedi, Kabupaten Klaten, Jawa Tengah.
