| You
may send us the designs in any format provided that the images
are clear and in good condition to process with digitization.
Clear artwork will allow the digitizing artist to give a precise
interpretation to the design. You may send art as vector image
or as bitmap image. For bitmap images, 300 dpi resolutions would
be enough to achieve good result. |

| 1)
Difference between vector and bitmap images |
| |
| Bitmap
artwork is comprised of dots (pixels) that represent a graphic
image, with each bit or group of bits corresponding to a pixel
in the image. When Bitmap image is enlarged, it produces jagged
edge and graininess, which is not print friendly. The bitmap
file is comprised of a series of dots per inch (dpi) and when
you enlarge a bitmap, rather than more dots being added, the
existing dots are simply enlarged. The larger the dots get,
the blurrier the image will be. Examples of Bitmap images are
JPG, TIF, BMP, PSD and GIF. |
| |
| Example |
| |
| While
Vector artwork is simply comprised of lines (wireframe) that
represent the objects. Vector images are usually created with
the drawing program such as CorelDraw, Adobe Illustrator or
Freehand. Increase or reduction in size will produce no pixelization.
The combination of one of these programs with an expert digital
artist can create a beautiful artwork that can be used on print
articles. Line art images are size independent. That means it
can be scaled up and down without losing any quality. The image
will be of same quality no matter what size it is being scaled.
Examples of vector images are CDR, AI, and EPS. |

Bitmapped
file (.BMP): The most basic type of graphics is the bitmap.
It is essentially a grid of dots- a mosaic made from many tiny
black and white or colored tiles or bits. Bitmaps have a fixed
grid-like or mosaic nature and can produce unsightly results
when an area of the bitmap is moved, enlarged, or rotated. When
you move part of the bitmap, you tear up tiles and put them
somewhere else, leaving a hole. If you enlarge a bitmapped graphic,
it looks like big dots. If you shrink the bitmap, some of the
tiles overlap others. Any change to a bitmapped image becomes
jagged and distorted.
JPEG: The joint Photographic Experts Group developed the Jpeg
file. This format was created for a standard for color and grayscale
images; it only works on continuous tone images. The big advantage
of this file is the compression that the file allows. It uses
a lossy compression scheme that will throw out data to compress
the file as much as 10:1.
One important characteristic that affects these files is the
compression scheme used to compress the file. Compression schemes
fall into two categories: lossless and lossy. Lossless compression
allows the file to be compressed without losing any data. Lossy
compression works by removing some of the data so quality can
suffer.
Corel Draw .CDR / Illustrator .AI: They are object-oriented
graphics. They overcome the limitations of bitmaps. The images
are composed of mathematically described objects and paths,
some strokes as a list of drawing instructions compiled from
menu choices and mouse actions. You can enlarge, reduce, rotate,
reshape, and refill without losing the quality. These graphics
are resolution-independent.
TIFF or TIF: Acronym for tagged image file format, one of the
most widely supported file formats for storing bit-mapped images
on personal computers (both PCs and Macintosh computers).
TIFF graphics can be any resolution, and they can be black and
white, gray-scaled, or color. Files in TIFF format often end
with a .tif extension.
Encapsulated Postscript (EPS): Is actually Postscript file with
a preview. It is used for storing both object oriented artwork
and bitmapped artwork. If an object-oriented image is saved
in the EPS format, it will retain its resolution-independent
printing quality, and in most cases cannot be ungrouped, refilled
or re-colored. It can be resized, distorted, or cropped.
Adobe Portable Document Format (PDF): It is an excellent file
format for file exchange due to its portability and cross platform
characteristics. It preserves the exact look and content of
the originals complete with fonts and graphics and can be printed
and distributed by email, share or store it on the web.

Create Outlines for Adobe Illustrator or Convert to Curves for
Corel Draw |

This
is a common problem in files compatibility. Your fonts do not
travel with your file and will default when opened in our system.
If these functions are not done, when we read the design, our
system replaces the font that you sent. So wrong font.
To avoid delays and possible errors please convert all text
to curves before sending files to us. The following screen shots
will inform you how to do them. If you have problem using these
functions, just export the files to be used as EPS format and
send it to us. This will solve your problem of using these functions.
