Full color items from RC Hill Publishing are printed using the CMYK color model,
which involves a 4 color process including Cyan, Magenta, Yellow and Black. Four
printing negatives or plates are created and the plates are keyed or aligned with
black. The four ink colors of varying intensity are applied in CMYK order. The "K"
in CMYK comes from the last letter in "black" and was chosen because B already means
All artwork and images must be provided in CMYK color mode for all color side(s)
and gray scale for the backside (if you choose 4/1).

Your computer screen displays images using RGB color model (Red Green and Blue).
We Require RGB-to-CMYK Conversion of Your Images: You must convert all of the images
from RGB to CMYK before sending them to us. When we receive RGB images, it is our
policy to try and convert your RGB images to CMYK, without contacting you about the
format of your submission. Please note that conversion to CMYK may cause colors to
During the CMYK conversion, we do our best to closely match the colors in your order.
However, RC Hill Publishing in no way guarantees that the colors in your converted
file will exactly match the colors of the images that you submitted to us in RGB
format. We will not be responsible for any imperfections due to your images being
sent to us in RGB format, as we require RGB-to-CMYK conversion of images.
Certain RGB colors when converted to CMYK become dark and dull like sample shown
All artwork must have a minimum of 300 DPI resolution.
Raster graphics, such as TIF and JPG files must have a minimum resolution of 300
DPI (dots per inch). Images with less than 300 DPI will reproduce poorly on the press,
causing the image appear fuzzy and pixilated.
When we receive low resolution images, it is our policy to try and convert all low
resolution images of 200 DPI or greater to 300 DPI, without contacting you about
the format of your submission. RC Hill Publishing will not be responsible for any
imperfections due to submission of a low resolution image, as we require all artwork
to have a minimum of 300 DPI resolution.
You should not use any images from an Internet web site, because the Internet displays
images at 72 DPI, which is low resolution and may result in loss of quality. You
should also not try to increase the resolution from a low resolution image to a higher
one by increasing the DPI, because this too will create a loss of quality.
We accept files with transparencies for printing. We recommend that you flatten all
submitted transparencies in order to avoid any possible problems. If you do not flatten
your transparency, we may flatten your transparency for you without contacting you
about the format of your submission and advance your job to print. RC Hill Publishing
is not responsible for the outcome of your transparency image.
Transparencies are caused by shadows, glows and transparent objects created in a
vector based platform such as Illustrator and InDesign. If a file containing transparency
problems is printed the result will be a white box under the transparent object.
While we understand that using these effects can sometimes enhance the appearance
of your design, the best way to avoid transparency problems is to not use the effects
that cause them. However, if you choose to use a transparency, we recommend that
you flatten your transparency. The following Instructions may also help you resolve
any transparency problems.
When an object(s) is set to OVERPRINT, any object directly underneath it, will print
on top of it. It is highly recommended to turn off OVERPRINTS that may be on any
object(s) or text.
FOR SOLID BLACK BACKGROUND: When you want an area of solid black within your document,
use Rich Black, as represented by C:50% / M:50% / Y:10% / K:100%, because using 100%
black (K) only and not a solid saturated black will result in a dull black.
FOR SOLID BLACK TEXT: When you want your text to be solid black, use these percentages:
C:0% / M:0% / Y:0% / K:100%, because using the the percentages for the Solid Black
Background, immediately above, on text, will result in offsetting.
The color blue consists of a color combination of Cyan and Magenta values. The higher
the Magenta value, the higher the risk of your blues turning purple. To avoid your
blues from turning purple we recommend the Magenta value be at least 35% lower that
the Cyan value. For example: 100% Cyan and 100% Magenta equals Purple. Although this
combination looks blue on your computer screen, it will print purple.
Due to our vendor’s employment of a printing method, called "Gang-Printing," RC Hill
Publishing DOES NOT GUARANTEE the accuracy of its printing reproductions, particularly
with respect to color variations.
Bleeds, Safety Zones and Borders:
All bleeds should be 1/8 of an inch (0.125) all around. If your submitted files are
missing a bleed, it is our policy to try and .TIF your files, in order to correct
the problem, without contacting you about the format of your submission and advance
your job to print. RC Hill Publishing will not be responsible for any imperfections
due to your submitted files missing a bleed, as we require print ready files.
Due to slight shifting that may occur during cutting, it is not recommended that
you add a border, as we do not guarantee that your border will remain the same size
after cutting. Particularly, when you add a border to a UV coated job, there may
be slight slipping that may cause some shifting during cutting.
In order to prevent your image (text or picture) from being trimmed or cut off, the
image must be 1/4 of an inch (0.25) from the edge of your layout.
Any images that are meant to extend into the edge of your design must extend into
the bleed area, within a minimum of 1/16 of an inch all around (0.0625").
Bleed is a technical term for printing that extends to the edge of a page. For example,
a business card is 3.5”x2", but we require a 1/16 (0.125”) bleed. Making the file
NOTE: Shifting of the blades may occur during the cutting process, which is why it
is crucial that submitted files have bleed. If submitted file/s don’t have bleed,
final printed piece will have white trimming around the edges.
It is recommended that you embed your linked files, rather than linking them directly
to the document.
If you do not wish to embed the linked files, you may choose to create a Press Quality
PDF of your document instead.
We require you send one file per side. Files sent with both front and back on one
page will not be accepted.
RC Hill only accepts files formatted for commercial printing in PDF. If you are unable
to format your file correctly, you may need to hire a prepress professional to ensure
your printing project prints as needed.
Outlined Fonts & Strokes:
When submitting PDF files to us, you must convert your fonts and strokes into outlines.
Outlining eliminates the need to send fonts along your files, while maintaining a
nice, crisp typeface. Outlining fonts may also avoid any problems associated with
Be sure to save your original file (with Live Fonts) separate and apart from the
version you outlined for printing, because if you save over your original document
with the outlined version you will no longer be able to edit the text.
