I am hereby documenting few of my thoughts about black colour behaviour on Physical Paper & on Computer Display or on Screen.
I was from BFA (Bachelor of Fine Arts) – Applied Art background so we had subjects like Illustration, Calligraphy, Typography, Print Media Design, Logo & Symbol Design, Branding & Identity Design.
We use to design our assignments using Japan Black ink which is vary dark in contrast & which creates high contrast reach feeling of black colour tone on white paper.
So when we print our designs done in Adobe Illustrator or CorelDraw we use to fill the design with (CMYK) Cyan: 100%, Magenta: 100%, Yellow: 100%, K(Black): 100% than using only K: 100%. This CMYK values use to create high contrast Japan Black ink fill on White Paper.
I will list down steps to secure your macOS & iOS Wi-Fi Network.
Step 01: First things first, Update you Macintosh, iPhone, iPad, iPod touch & even AirPort Express, Airport Extreme base stations for latest software using Mac App Store.
Step 02: Choose Unique & Safe SSID (Service Set Identifier) Wi-Fi network name
Wi-Fi network name is case sensitive. Choose a unique name for your network and that isn’t shared by other nearby networks. If your SSID isn’t unique, Wi-Fi devices will have trouble identifying your network. This could cause network device to fail to automatically connect to your network, or to connect to other networks sharing the same SSID.
Here is simple solution to create single PDF by combining multiple files from various files types.
Assumption: I Assume you have 10 png files that you want to combine in to single PDF file.
Note: It really doesn’t matter if those 10 files have different height & width dimensions.
Here is how to do this:
Step 01: Locate & Open Preview in Applications folder on your Macintosh
Step 02: Select Preview now go to File > Open
Step 03: Select & Open all desired files in Preview
As Wikipedia Says: Disk Utility is a system utility for performing disk and disk volume-related tasks on the OS X operating system by Apple Inc.
Day to day functions supported by Disk Utility are:
- Creation, conversion, backup, compression and encryption of logical volume images from a wide range of formats read by Disk Utility to .dmg or, for CD/DVD images, .cdr
- Mounting, unmounting and ejecting external disk volumes
- Enabling or disabling journaling
- Verifying a disk’s integrity, and repairing it if the disk is damaged
- Erasing, formatting, partitioning and cloning disks
- Secure deletion of free space or disk using a “zero out” data, a 7-pass DOD 5220-22 M standard, or a 35-pass Gutmann algorithm
- Adding or changing partition table between Apple Partition Table, GUID Partition Table and master boot record (MBR)
- Restoring volumes from Apple Software Restore (ASR) images
- Checking the S.M.A.R.T. status of a hard disk
- Disk Utility functions may also be accessed from the OS X command line with the diskutil and hdiutil commands.
Now will learn how to partition disk,
Important Note:
- Partitioning a disk erases all the data previously stored on it
- By using partition feature of disk utility it divides disk into sections called ‘partitions’ which appear on the desktop as separate disks.
Precaution: Before moving forward backup all your computer data using Time Machine on different hard drive other than that you are currently partitioning.
Step 01: Connect External Disk to your Mac using USB / FireWire cable for purpose partitioning it
Step 02: Locate ‘Disk Utility App in Applications > Utilities
