RGB vs CMYK. How to produce a more consistent color scheme for your printouts?

What you see on your RGB monitor isn't the same as your printout? How come my screen looks so much brighter than my printouts? If then, how to produce a consistent or the color that I want?

It boils down generally to initial preparation, understanding RGB-CMYK and color management.

Initial Preparation

Getting the right setup is the first step. Let go thru the checklist:

1) Working with a low color gamut monitor or using overpowered 4K display monitors.
2) Calibration between your monitor and  the printing devices or print server like the EFI Fiery.
3) Using the right color profiles
4) Have comprehend the spectrum of your printer color output.
5) Using the wrong profile or RGB setting on your working files.
6) Doing actual physical print proofs.

Understand the RGB-to-CMYK

You will get a more "color feel" of the appearance of your printed piece if you convert or work your files from RGB to CMYK. Difference software, printserver or printers might have different profile and might do the auto-conversion to CMYK for printing differently that what you are expecting.By the way, don't even think of printing certain pantone color (spot color) such as metallic or colors that a regular 4 color - CMYK printer not able to produce. Different printers have their own color spectrum and technology. Take note that RGB color might be viewable on your screen and doesn't mean it is able to be reproduce. 

Here's a common example: many programs translate the 100% Blue in RGB into a somewhat purple-looking color in CMYK. We recommend a CMYK value of 100-65-0-0 to get a nice clean blue. Working in the CMYK color space allows you to select the CMYK recipe, or "screen build", that gives you the results you want.
Here are some examples of how various RGB colors convert to CMYK:

Color Management and Reproduction

For more details of color management and reproduction, you can always refer to your professional commercial printers. Accept the fact that the digital space and physical (the hardcopy or output) is not going to be the same. Similar is what we are aiming for. 
Did you know that  that two individuals can look at the same object and have the same wavelengths hit their eyes, yet “see" different colors? 
There are multiple devices involved in image production, and not just from the digital world. Knowing the available printing methodology, machine technology, theirs strengths, their limitations and most of all the production-cost-vs-time .
Printing production is both ART and SCIENCE. Of course, hell lot of experience in trial and errors. Not all pixels are created equal. Not all media are always the same and not everyday your supplies are 100% same as what you have bought last round. Humidity and temperature also plays a part besides the actual handler. 
It’s important to remember that any printing process or technology has its limitations. No matter how industrial or state of the art of the machinery, it still faces its limitations and constraints. For the past 20 years, the printing technology has evolved a lot but it still boils down to the printing fundamental since 2000 years ago. 

Build a cheap productive Desktop PC for graphic designers for less than USD $700.

02 April 2020

Getting a standard PC from Dell, HP or even Alienware does not give me the right value of money vs the productivity requires for a regular graphic designers. Today, I will specifically spec out the cost effective & efficienct PC build up for 2D graphic type / Non Video Rendering type; specifically for graphic students, printing, media and communication industry. 

Software usage includes Adobe Illustrator, Photoshop, Indesign, Acrobat, Autocad and of course Microsoft Office such as Word, Excel, etc.

By the way, we are not building for gaming and gaming usually focuses on graphic cards, multi cores and Z motherboard for tweak processors. 

Let's start with a target price between USD $600 to below $750 (RM 2400-3000) 

Will start with a motherboard (MoBo) - a B series or even H series will do as long as it has 4 slots of ram. Asus, MSI or Asrock are well tested and compatible with quite rangeof hardware. Price about USD $100 (RM 430). 

Second most important is the processor and get the processor with the highest GHz, but limit the core cause more core more $$ and yet 2D will not render efficiently via multi cores. Will choose Intel over AMD due to more support for our application via Intel comparing to AMD (more for games). Moreover, Intel pricing has went down quite a lot due to AMD Ryzen release in these recent years. In this scenario, I will choose the i5 9400F (price USD $170). If you have more budget, an i7 will be great and you can also omit the graphic card as the in built is sufficient. Will explain why later. 

Then, will pair the cheapest available graphic card and even an older GT710 will do (about USD 75) or any card with not more than 35watt. Surely save electric bills in the long run. A external graphic card will off load some processing/memory from the system but not significant as RAM and Hardisk play a more vital role. 

Thirdly, the memory, DDR4 ram,  2333mhz or above and will need at least 16GB or in my built of 2 x 8GB ($70+). Can always upgrade additional RAM if needed. 

Next, will need 1x 256gb of m.2 SSD hardisk (price $40) at read/write 3000mbps for your OS and 1x 1TB SATA for working storage purpose, if needed. Omitting it if you are using cloud storage or external NAS. 

Others required will be a PSU (power supply) at min 300watt ot max 450watt (price $ 40). Lesser watt is better as this will save significant cost of your yearly electric bill. A nice casing with additional fan ($100), Fractal Design's mini ITX or small tower will do for me. Like it small and stylo. 

Future upgrade if needed would be of course RAM to 32GB. It will be the cheapest yet significant upgrade. Next could be a faster/bigger SSD storage. Of course can upgrade a mightly graphic card if video rendering is required. 

So far, my built is about USD$650 excluding the Windows 10 OS and a good monitor. 

Hope that you like this post. If there is any question regarding hardware compatibility, OS or merely discussion, feel free to drop me a comment.
