In this experimental work, an extensive investigation had been carried out on AL 19000-H12 grade aluminum alloy plates. Plates of aluminum alloy (AL19000H12) size 200x50x6 mm were used for experiment. Material of weld tool used high carbon steel Diameter of tool head used 17 mm and length 50mm. Four different tool pin profiles (Straight cylindrical, Square,(More)
By taking into account the properties and limitations of the human visual system, images can be more efficiently compressed, colors more accurately reproduced, prints better rendered. To show all these advantages in this paper new adapted color charts have been created based on technical and visual image category analysis. A number of tests have been(More)

ABSTARCT With the advent of digital images the problem of keeping picture visualization uniformity arises because each printing or scanning device has its own color chart. So, universal color profiles are made by ICC to bring uniformity in various types of devices. Keeping that color profile in mind various new color charts are created and calibrated with(More)
The production of a printed product involves three stages: prepress, the printing process (press) itself, and finishing (post press). There are various types of equipments (printers, scanners) and various qualities image are present in the market. These give different color rendering each time during reproduction. So, a color key tool has been developed(More)
The main problem in colour management in prepress department is lack of availability of literature on colour management and knowledge gap between prepress department and press department. So a digital test from has been created by Adobe Photoshop to analyse the ICC profile and to create a new profile and this analysed data is used to study about various(More)
Speech signal carries the information about the linguistic message. Speaker-specific information is also contained in speech signal. No two peoples voice are exactly alike because voice has fingerprint qualities. It is generated by acoustically exciting the cavities of the mouth and nose, and can be used to recognize (identify/verify) a person. The work(More)
