Rotogravure

Rotogravure is a printing technology in the world. Rotogravure alone in the world of print graphics means. Or in layman language is the printing technology used to print media made of a flexible material (eg; various types of plastic, aluminum and paper and PVC). Materials to be printed is in the form of rollers or rolls. Results from the rotogravure printing is not directly can be enjoyed by consumers, but must go through several stages, as follows (eg manufacture of snack packs of children); 1. Plastic laminated printout by placing first in print rollers to laminate machine, then the plastic rollers are coated with adhesive and attached to other media in the form of "metalize" (a mixture of plastic material coated with aluminum). 2. Results that have been laminated rolls and then dried (in the "aging") first. 3. Rollers that have been dried and then taken to the machine "slitter", to cut long, wide rolls into a certain size in accordance with orders from the snack manufacturer. The above process only a brief description, behind it is still a lot of technology used in the world to produce a rotogravure packaging. Starting from design, making cylindrical tubes of iron, copper coating, making the picture above has a metal cylinder covered with copper, chrome coating, printing, inspection, lamination, slitting (cutting), making bags (if that orders sent form pockets) and many longer process therein. Because in the process changing the form of raw material into a material, usually this process is called process of "converting" or in other words, is "converting industry" As for some everyday examples of converting the result is, as follows: 1. 2 packs of instant noodle. Packaging of drugs (other than the capsule and syrup and eye drops) 3. 4 snack packs. Water bottle label bottled mineral water and isotonic (called shrink label) 5. Close mineral water drinks, etc. (cup lid) 6. Rotogravure and the like can also be used to produce magazines, folding box, gift wrapp and beverage labels with special equipment can be done in line. Excess rotogravure printing process compared to other can be used to print in rolls of a width ranging from 20 cm (labeling) to 1100 cm (vinyl floor) with a length of more than 5000 m depending on the material used. Similarly, the type of materials used vary widely, ranging from plastic film 12mc to 320 gsm cardboard. While the weakness of the rotogravure is not as sharp image quality offset and text structure formed from the dot.

Color Setting [Photoshop] to print

Color settings in photoshop is essential for the necessary (in fact, without setting the color / color settings can for print), for each printing (possible) its color settings to the usual variations I did the first time using adobe photoshop / after installation..
1. edit === > color setting">Go to the menu ===> === edit> color settings

2. Window will appear as follows :



In the Working Spaces column select the RGB mode select Apple RGB

3. Still in the field Working Spaces select the CMYK (CMYK custom ...) will appear the following window:



On separation Options arrange as follows:



Separation Type : GCR
Black Generation : Light
Black Ink Limit : 80 %
Total Ink Limit : 360 %
UCA Amount : 0 %
when finished click ok

Note: if you want to print only the 3 colors (CMY) living instead (in black generation) to None. Or fox value in Black ink limit to 0%

Print Filter (Sablon)

Print filter or what we usually call Sablon is one of the techniques of the printing process using screens (screen) with a certain density and are basic barbahan Nylon or silk. This screen is then given polafotoresis and lit, will form the parts that can be passed and not ink. negative from the previous design made. This cloth is stretched tightly in order to produce the printout screen and flat. Having given

The process of execution is by pouring ink on the screen and then washed using a palette or rakel made of rubber. One screen is used for one color.

color calibration on the monitor

In the world of graphic (print) adjustment / monitor color calibration is important, although now the average of all computers are supported by the VGA card and monitor the quality good enough, but still recommended color calibration therefore try to calibrate the colors on the monitor so that the results (printed) in accordance with what we expect. For people / consumers that the average layman they assume that what they see on the computer exactly as it results in print and they do not understand (the difference) between the monitor (RGB) with offset printing (CMYK). All images (color) that appear on the monitor would have decreased the quality of color distortion even if only slightly. The way I usually do to set the color calibration is through the Adobe Gamma is usually found in Control Panel but with conditions already have Adobe Photoshop installed first (I understand that if we install the Adobe Photoshop CS3 only 7 or adobe gamma do not appear on the control panel) is strongly recommended to install a minimum of Adobe Photoshop CS1 or if the computer with minimum specifications rather better series to install Adobe Photoshop 5.5 (which I think is very good compared to series 7). In regulating the color calibration is tricky because we need to know and (on average) should use our feeling of how the image / colors that appear on the monitor when you do not see eye feels hot to cold and other words according to (fix) the results that in print.

Introduction to Software Design Graphic Print Process

Design is a series of good ideas shedding process is described either manually or processing images / layout with the help of computers until ready for processing in this case ready for print.

In this case (computerized) is known by the term 2 Picture element (called Pixel) and Vector (line) both support each other. Difference between the two is that Pixel will depend on the name resolution while the vector did not. This means that if the image that have the Pixel low resolution if raised will be seen broken while growing up any vector will not break and if we print will be very clear difference between the two.

In the world of Design (print) known to a lot of software that supports the processing of images and layouts.

A. Layout processing software (layout)

1. Adobe Page Maker
2. Adobe in Design
3. Adobe Frame Maker
4. Corel Ventura
5. Microsoft Publisher
6. Quark Express

This software is usually for the need to make magazine pages, books, newspapers etc. in a very flexible because it can regulate the placement of text and images.

B. Vector Image Processing Software

1. Adobe Illustrator
2. Macromedia Freehand (there is no new version since been acquired by adobe)
3. Corel Draw
4. Etc.

The software used for the purposes of making logos, calendars, brochures, etc.. Actually (for CorelDRAW) was also able to arrange the layout of newspaper pages in magazines, books, etc., depending on ourselves.

C. Pixel Image Processing Software

1. Adobe Photoshop
2. Corel PhotoPaint
3. Macromedia Xres
4. Etc.

This software is usually for editing photos, either for retouching or image manipulation

Blending Mode

Select from the pop-up mode selection menu in the bar (layer).
Note: Only Normal, Dissolve, Dark, Multiply, Lighten, Linear Dodge (Add), Difference, Hue, Saturation, Color, Luminosity, Lighter Color, and mixtures Darker colors are available for 32-bit mode images.

Normal : Each color pixels to the result. This is the default mode. (Normal mode is called Threshold when you're working with a bitmapped or indexed-color images.)

Dissolve : Each color pixels to the result. However, the result is the replacement of random color with the basic color or mixed colors, depending on the opacity at each pixel location.

Behind : Only the part of the layer transparent. This mode works only in layers with Lock Transparency deselected and in line for a picture on the back of transparent acetate sheet on the area.

Clear Edit or made transparent. This mode is available to Shape tool (when fill region is selected), Paint Bucket tool, Brush tool, Pencil tool, Fill command, and the Stroke command. You should be in layers with Lock Transparency selected using this mode.

Darken : the color information in each channel and select a basic color or a mixture of dark-which-as a result of color. Pixels lighter than the blend color are replaced, and pixels darker than the color of the mixture unchanged.

Multiply : color on any information in the channel (channel) and multiplying the base color with the color combination. The result is a color that is always dark. Multiplying any color with black produces black. Multiplying any color with white leaves the color unchanged. When you paint with colors other than black or white, successive strokes with a painting production equipment became darker color. Effects similar to pictures in a picture with some marking pen.

Color Burn : the color on the color information in each channel and darkens the base color to reflect the blend color by increasing the contrast. Mixed with white produces no change.

Linear Burn : the color information in each channel and darkens the base color to reflect the blend color by decreasing the brightness. Mixed with white produces no change.

Lighten : the color information in each channel and select a basic color or a mix-whichever is lighter-color as a result. Dark pixel color combination compared with the replaced, and pixels lighter than the color of the mixture unchanged.

Screen : at each color channel and multiplies the inverse of the information base and blend colors. The result is always a light color colors. Screening with black leaves unchanged. Screening with white produces white. Effect similar to a slide projection of images on top of each other.

Color Dodge : Looks at the color information in each channel and brightens the base color to reflect the blend color by decreasing the contrast. Produce a mixture of black with no change.

Linear Dodge (Add): the color information in each channel and brightens the base color to reflect the blend color by increasing the brightness. Produce a mixture of black with no change.

Overlay : multiply or color screen, depending on the basic color. Patterns or colors overlay the existing pixels while preserving the highlights and shadows of the basic colors. The basic color is not replaced, but mixed with the blend color to reflect light or dark color original.

Soft Light Darkens or lightens the color: color depends on the mix. Effect similar to the diffused spotlight shines on the picture. If the color of the mixture (light source) is lighter than 50% gray, the image alleviate the inevitable. If the blend color is darker than 50% gray, the image burned in the dark as Painting with pure black and white or typical regional produce dark or light, but did not result in pure black or white.

Hard Light : multiplying or light color display, depending on the blend color. Effect similar to shining a sharp spotlight on the picture. If the color of the mixture (light source) is lighter than 50% gray, the image ease, as screened. This is useful for adding photos to the highlights. If the blend color is darker than 50% gray, dark images, as multiplied. This is useful for adding shadows to an image. Painting with pure black or pure white or the black and white.

Vivid Light Burns or dodges the color : the increase or decrease the contrast, depending on the blend color. If the color of the mixture (light source) is lighter than 50% gray, the image contrast alleviate the decline. If the blend color is darker than 50% gray, dark images with increased contrast.

Linear Light Burns or dodges the color : by decreasing or increasing the brightness, depending on the blend color. If the color of the mixture (light source) is lighter than 50% gray, the image brightness by increasing ease. If the blend color is darker than 50% gray, dark images by decreasing the brightness.

Pin Light : replace color, depending on the blend color. If the color of the mixture (light source) is lighter than 50% gray, pixels darker than the blend color are replaced, and pixels lighter than the color of the mixture unchanged. If the blend color is darker than 50% gray, pixels lighter than the blend color are replaced, and pixels darker than the color of the mixture unchanged. This is useful for adding special effects to photos.

Hard Mix : Adding the red, green and blue channel values to RGB color mix of primary color values. If the amount generated for the channel is 255 or more, which receives the value 255, if less than 255, the value 0. Therefore, all blended pixels have red, green, blue and channel values either 0 or 255. This all changes to the pixel primary color: red, green, blue, cyan, yellow, magenta, white, or black.

Difference : difference in colors on the information in each channel is good and reduce the color combination of the basic color or base color of mixed colors, depending on the greater brightness value. Mixture of white inverts the base color values; mixed with black produces no change.

Exclusion : Creating effects similar to but lower than the contrast difference mode. Mixture of white inverts the base color values. Produce a mixture of black with no change.

Hue : Creating results with bright colors and basic color saturation and hue of the color combination.

Saturation : Making the results with bright colors and basic colors and color saturation of the blend. Painting with this mode in areas with no (0) saturation (gray) causes no change.

Color : Make due with bright colors and basic color hue and saturation of the blend color. This preserves the gray-level image and is useful for coloring monochrome images and for tinting color images.

Luminosity : Making the results with color and basic color saturation and brighter colors than the color combination. This mode creates the effect of inverse color mode.

Lighter Color : comparing the total of all channels to the basic values and the combination of colors and displays a higher color values. Light colors do not generate the three colors, which can result from the combination of relief, because choosing the highest channel of the two basic values and blend colors to create the color.

Darker Color : comparing the total of all channels to the basic values and the combination of colors and color display lower values. Dark colors do not generate the three colors, which can result from the combination of darkness, because choosing the lowest channels of the two basic values and blend colors to create the color.
