Scanners, digital camera, computer monitor and other displaydevices use the RGB (red, green, blue) color mode, while in [link widoczny dla zalogowanych] theprinting process CMYK (cyan, magenta, yellow and black) colormode is used. Meaning, you have to expect change in the color ofthe image when you print it. To reduce the problem, you mustconvert your image from RGB to CMYK. There are image editingprograms [link widoczny dla zalogowanych] that offer color conversion, such as Photoshop or [link widoczny dla zalogowanych] CorelPhotoPaint.
To clearly see the difference of the quality of image on screenand on print, take an image from the internet. Zoom it out ormake it larger. Can you see how series of little squares appearon the image? Try to print it and you'll see that the color willfade. There will be a change in the resolution.
When you extract images from the internet, most probably, youwill [link widoczny dla zalogowanych] have a poor quality image. Internet images are mostly savedin GIF or JPEG file format, which only consumes 72dpi. Thepurpose of saving image files on this resolution is to make theimage easy to [link widoczny dla zalogowanych] extract. Meaning, these images are not for printuse.
Resolution is, basically, the sharpness or crispness of animage. When an image is [link widoczny dla zalogowanych] shrunk, the color looks lively. [link widoczny dla zalogowanych] When youblow it [link widoczny dla zalogowanych] or enlarge it, the color will fade and the image willlook unclear.
Do not expect to get good images from the internet. You mustresort to other sources like real photos or pictures frommagazines. When you scan, compare the size of the photo to thesize of your layout. If the photo is larger than your layout,scanning at 300dpi is enough. If it is smaller, adjust yourscanner's resolution setting and percentage size. If [link widoczny dla zalogowanych] there aretexts over the image, lighten the image [link widoczny dla zalogowanych] so the text will bereadable. If you do not know how create good prints, you canresort to a printing press.
Resolution is defined as the number of pixels contained in themonitor. Pixel, from the words "picture element", is the basicunit of programmable color in a computer image. The resolutionis measured by the number of dots per inch (dpi), which is equalto the numbers of squares of color in an inch. A standardresolution for an image should be 300dpi and 400dpi for imagescontaining [link widoczny dla zalogowanych] text.
Does your image appear good on the screen, but looks blurred,jagged [link widoczny dla zalogowanych] or fuzzy when you print it?
The resolution of an image is [link widoczny dla zalogowanych] inversely proportional to the sizeof the image. In other words, when you increase the size of [link widoczny dla zalogowanych] theimage the resolution decreases, and vice versa. For example, ifyou enlarge an [link widoczny dla zalogowanych] image, the size, of course, increases. But thequality or sharpness of the image decreases, giving you ablurred image.
