CONCEPT OF COLORS

NATURAL COLORS
Black and white is called natural colors
White indicates the light
Black indicates the absence of light

PRIMARY&SECONDARY COLORS

RED, GREEN & BLUE are the primary color
VIOLET,ORANGE & GREE are secondary color
i e the color obtained from the mixture of Primary color

THE TERTIARY COLORS
If any two secondary colors are mixed in equal proportion is called Teritiary color

ANALOGOUS & COMPLEMENTARY COLOR
Analogous colors are nearly like one another and close together on the color wheelComplementary colors that are positioned opposite to each other in the color wheel

TINT & SHADES
Tint is obtained by mixing white color
Shade color is obtained by mixing the black color.

LOW KEY AND HIGH KEY
A picture is painted in the graded order of shades, it indicates a dark state then such color scheme is known as heavy scheme or low key

A picture is painted in the graded order of tints, it indicates a bright state then such color scheme is known as light scheme or high key

COLOR DEPTH
Image quality depends on color depth in expressed in “bits”and Quality images are stored in 24 bit

COLOR HARMONY
In A color harmony refers to combined effect of various colors as they appear next to each other in printing

WARM AND COOL COLORS
Red ,yellow,orange and brown are called warm colors
Blue,green and violet are called Cool colors

HUE & SATURATION
The colors that we perceive in the rainbow is called hue
The intensity oc color is called saturation

ABOUT PRINTING

Printing in its broadest sense, is any process whereby one or more copies are produced from master image.Image transfer from master to copy is usually accomplished with inks and the transferring agent is a mechanical press.Most commercial printing is achieved through one of the following process. They are Relief printing, Offset Lithography and Gravure printing.

PRINTING PROCESS AND TYPE

Tthe printed communications begins with a plan that is followed by or jointly prepared with the words and illustrations needed to accomplish the goals of the communications.
•Due to the invasion of digital media (offset printing) made the production
•Even more preparing printed media using computers.
•We have many process, but the best is Photo offset Lithography or offset process. This uses metal images to carry ink to paper from a flat surface.
•Offset printers work with the basic principle that water won’t mix up with oil. The printing plate holds ink because the image area is treated so that it is receptive to oil based ink not to water.
•A multi-color offset press has a separate printing unit for each ink being printed.

•The steps involved are:-
Plate making.
Wetting.
Inking.
Offsetting.
Printing.
•Wetting is a process in which the plate is mounted on a rotating cylinder. When the press starts, the plate comes into contact with the water rollers first.
•Dampening solution flows constantly from a tray like fountain through series of rollers wets the entire printing plate, except where the plate has been treated to resists water.
•Plate making is a process whereby a printer exposes the reversed image from a film separation (negative) onto a flat plate with light-sensitive coating, and then develops the plate.
•The image area of the plate — now a readable positive is coated with a chemical that attracts ink but repels with water.
•Offsetting is where the final roller, which is a rubber blanket, will be pressed against the printing plate and carries away a reversed inked image.
•The rubber blanket has some flexibility and gives slightly when pressed against paper, so the image can transfer evenly to both smooth and textured paper.
•Printing -In the last step, the paper in individual sheets or on a continuous roll passes between the rubber blanket and an impression cylinder.
•The inked blanket cylinder with its reversed image presses against the paper, printing the +ve image.

CALIBRATING YOUR SYSTEM

The first step in Color separation is calibrating Our devices (monitor, printer, scanner) and have Correct system-wide color calibration.

Calibration is of two types viz, device calibration And system calibration. Device calibration works with monitor and making adjustments for the image setter that we’ll use when we do color separation.

System calibration is adjusting the Adobe Photoshop settings that affect the image when it has been converted from RGB to CMYK.

Calibrating an image won’t affect it in RGB, because monitors are RGB devices. Changes are only for CMYK. Don’t set changes in CMYK, always comes to RGB and then change the mode.

Producing a best scan.

Although Photoshop corrects scanned images, it cannot correct images which doesn’t have much color details init — either because it was scanned at a too low resolution or because it lacks detail
In the highlight and shadow areas.

To make good second originals, do the following steps properly:

Steps
Determine the exact scan resolution for according to your requirements.

Take care of size of the image according to the scan resolution.

Scan always by using the file size settings.

Eliminate the unwanted color casts by calibrating Your monitor.

Separation setup adjustments.

The settings in the Separation Setup dialog box along with the settings in Printing Inks dialog box control how CMYK plates are Generated.

The Separation settings include the method used for Black generation, under color removal and total ink limit for the press.

When Adobe Photoshop converts an RGB image in to CMKY mode, the program converts the values Using information in the Monitor setup, Printing ink setup and Separation setup dialog boxes.

The first two settings will provides a closest match for the onscreen and final output image. The separation Setting will give the precise CMYK value chosen for a given RGB color.

Color separation is based on the principle of translating the three additive colors — red, green and blue — into their subtractive colors- Cyan, Magenta and Yellow. Theoretically, equal
Parts of cyan, magenta, yellow combine to Subtract all light and create black. Due to certain impurities present in all printing inks, however a mix of these colors instead yields a muddy brown.

To compensate to this deficiency, we add black ink to the final image output.

There are many ways that a given color can be translated from RGB mode to CMYK mode. Pre-Press operators typically use one of two styles of color translation. They are

1.Under Color Removal (UCR)
2.Gray Component Replacement (GCR)

For both UCR and GCR, the black generation uses the ink settings we enter in the Separation Setup Dialog box. (Black ink limit is 100 and total inkLimit is 1000.)

MULTIMEDIA SOFTWARES
Multimedia software emerged in mid-80’s, soon after the cd-rom was invented. Cd-rom with its vast storage capacity, has been compared in significance to paper, the printing press, and photography. By the early 1990’s the Multimedia phenomenon was gathering momentum and attracting great media interest; by the mid 1990’s Multimedia software was finding its place on the internet. Even if Multimedia does not live up to all the hype it is already a Multibillion dollar industry, creating hundreds of new titles each month. Many of these titles put computers to uses that could not have been anticipated when Multimedia first took off.

SOFTWARE USED TO PRODUCE GRAPHIC
The graphic means the still picture or image, in these there are two type vector and raster. vector is what we draw with sharp edges and raster is using pixels Vector graphic is done using software -illustrator In case of raster we use- photoshop.

Let you create editable vector shape and text. There are many tools for a variety of a vector based shapes. These tools can be used to create shape layers . photoshop includes new type formatting controls and cool fonts effects .you can slice web graphics in photoshop now.

FEATURES OF PHOTOSHOP
The facility to work with layers ,the number of predefined set of filters, masking, twain compatibility (the functionality of direct picking up of images from scanner), the ability to convert images to high resolution ,the facility to add gradients to your work, the ability to change color channels form rgb mode to cmyk mode.We also looked for the drawing tools that allows the inclusion of diagrams in the work without having to minimize the photo editing software and open a separate drawing software .

COLOUR MODES
There are two popular types of color modes: RGB & CMYK. The rgb mode consist of three color channel (red, green and blue). This mode is called the additive color mode as the red ,blue and green colors are mixed in different proportions and intensities to create white color.Although every person work in RGB mode when working with Images, the final image is changed to CMYK mode when it goes for printing ,which consist of four channels :cyan, magneta, yellow and black.

VECTOR GRAPHICS
Vector graphics is the creation of digital images through a sequence of commands or mathematical statements that place line And shape in a given two dimensional or three dimensional space. The file that results from a graphic artist work is created and saved as a sequence of vector segment

RASTER GRAPHICS
Raster graphics are digital image created or captured (for examples by a scanner in a photo) as a set of samples of a given space. The raster file is sometime referred to as bitmap because it contains information that is directly mapped to the display grid. A raster file is usually larger than a vector graphics image file . it is usually difficult to modify without loss of information , although these are software tools that can convert a raster file in to a vectir file for refinement and changes

Examples of raster image file types are:-
1. BMP
2.TIFF
3. GRAGHIC INTERCHANGE FORMAT(GIF)
4.JPEG

Seamless integration of multiple media elements in to one’ is called multimedia
Where multimedia stands in IT?
The overall structure of Information Technology (IT) can be classified in to two sections, Logical sections and creative sections. A person who has good talents in logical thinking should not be good in creative thinking because it is the human nature. All types of software developments come under logical section where as multimedia come under creative side. 'Seamless integration of multiple media elements in to one’ is the standard definition of multimedia. It is a combination of Design, Text, graphics, animations, film, video, Games, Photography, Illustrations, Printing, Fashion designing, Architecture, Engineering, Editing, Advertisement, Entertainment, Simulation etc. Comparing to all other fields, multimedia has a very bright future. The scope and the employment opportunities offered by the multimedia are very vast. But a creative talent is necessary to survive in this field.

..............If you are a beginner and looking for a brightest future in multimedia, I will ready share you some valuable knowledge and advice about multimedia industry.
