折光网版印刷制作工艺

折光印刷又称反光图纹印刷，其中的折光实际上是指反射光，而非折射光。折光印刷利用光的镜面反射原理实现其特殊的装饰效果。它是一种采用光反射率高的材料作基材，经过精心设计并制成折光印版，将折光版通过一定压力压印在印品上，从而形成有规律、凹凸状的图文，这些图文在光的照射下．能够产生有层次的光折射闪耀感以及二维立体形象的独特效果。

标牌面板工艺的新进展

标牌面版行业，现在发展很快，进步很大，和国外的标牌面板的制作水平比较，差距正在缩小，国外标牌面板制作水平，日本和韩国占领先地位。现在在国内市场和相关的展览会上，可以看到各种各样的标牌面板，花样非常多，国内国外的都有，这些标牌面板从工艺上归纳一下大约有20种左右。这些工艺相互结合，并用不同材料和不同的表面处理，制作出了多种多样的标牌面板。这些新的标牌面板，有的是老工艺采用了新技术、新材料、新设备创出了新水平，有的应用了新技术、新材料、新设备、新工艺制作出了新的标牌面板。这些标牌面板工艺的新进展都依赖…     

牌匾及其制作工艺(一)

牌匾，并不像一般产品所使用的铭牌，需要依附着产品，成为产品不可分割的一个组成部分．而它是一种独立的标志性铭牌，常用于奖牌、匾额、授权牌等。由于它的作用与形式的特殊性，目前已发展为铭牌中的一大门类。     

烟酒礼品包装盒的网印工艺

随着商品经济的发展和人们生活水平的提高,对包装装潢印刷提出了更高的要求。由于平版、凹版、凸版印刷有其自身的局限性,而网版印刷以其墨层厚、印压小、版面柔软、承印材料广泛等特点,在高档产品包装中发挥了优势。尤其是近年来在烟、酒、礼品包装中采用了蚀刻、冰花、折光(镭射)网印方法,与传统的印刷包装相比达到了质的飞跃,其特点是色彩艳丽、豪华、典雅,是高档名优产品理想的包装印刷方式。目前,仿金属蚀刻、冰花纹理、折光(镭射)等网印系列包装盒市场看好,并在扩大。由于网印技术与设备材料的开发和引进,国内一些网印厂家能利用新技…

Imitation Cheese Manufacture Using Rapid Visco-Analyzer and Its Optimization

Imitation cheeses in a laboratory-scale (100-g) made by a rapid visco analyzer (RVA) at different stirring speeds (200, 300, 450 rpm) were investigated with a control (Stephan cooker at 1,500 rpm) at 85 °C through functional properties, microstructure and sensory evaluation. Compared to the cheeses made by the Stephan cooker, the cheese made by RVA was significantly (P < 0.05) more green, more yellow and noticeably less white than all other cheeses, which had a decrease in the L* values and an increase in a* and b* values. TPA values of imitation cheese made by the RVA at 450 rpm were lower than that cheese made by other speed. However, the imitation cheeses of 450 rpm was significantly (P < 0.05) higher, which was similar with the fat leakage of imitation cheese manufactured by Stephan cooker. The melt of imitation cheese significantly (P < 0.05) reduced by increasing the stirring speed of RVA. While significant, the melt of the 1,500 rpm cheese was smaller than all other cheeses. Increasing the stirring speed of RVA showed a more effective fat emulsification and a uniform protein matrix. Sensory analysis showed the imitation cheese made by RVA at 450 rpm was similar to the control made by Stephan cooker. Subsequently, the stirring speed, mixing time and heating temperature were optimized at 450 rpm, 7.50 min and 86 °C by response surface methodology (RSM). Results indicated that RVA could make imitation cheeses as well as the functional properties of the control in a laboratory-scale.

Reflective practice and conscientisation

Both 'the reflective teaching' and 'the teacher as a reflective practitioner' have become very popular in terms of the literature about the teaching and training profession, in spite of ambiguities and misleading ideas. Thus, it is of the greatest importance to analyse these ambiguities by questioning the words used, the relations of power which are established among teachers, educators and trainees, the ways and effects of the reflection. To avoid the reflective action becoming a collection of techniques, a reflective practice should be based on an educational and training theory which should stimulate the teacher to take critical consciousness of the educational situations and of his/her own practice in the situation. The concept of conscientisation by Paulo Freire, linked to his concept of praxis as a dialectic unity of the theory and practice, should produce an instrument of theoretical and operational value for education. That concept will allow interpretations which will take the teacher to wonder about him/herself, about the world around him/her, promoting a critical and dialogist relationship towards the world, the others and him/herself. This dialogue, which cannot feed itself but feeds on the fusion of theory and praxis, will overcome the apparent dichotomy between technical and practical reason.
