Cara membuka file Excel yang dikunci / dilindungi
It is quite frustrating when you have an important Excel sheet to work on, but you cannot access it due to password protection. Here are a few methods to unlock or unprotect your Excel file:
Method 1: Using the Excel Password Recovery Tool
If you have forgotten your password or are unable to unprotect the sheet, you can use the Excel Password Recovery Tool. This tool is specifically designed to unlock protected Excel sheets. Follow these steps:
- Download and install the Excel Password Recovery Tool on your system.
- Launch the application and click on the ‘Open’ button to select the protected Excel sheet.
- Select a password range and recovery mode. Then click on the ‘Start’ button to begin the recovery process.
- Wait for the tool to recover the password. You can then use the password to unprotect the selected Excel sheet.
Method 2: Using the ZIP file method
This method is useful when you do not remember the password for the Excel sheet. Follow these steps:
- Right-click on the Excel sheet and select ‘Copy’.
- Create a new ZIP folder on your desktop and paste the copied file into it.
- Right-click on the ZIP folder and select ‘Rename’. Change the file extension from .zip to .xlsx.
- Open the newly renamed file, and the password protection will be removed, allowing unrestricted access.
Mengapa Warna Hasil Cetak Berbeda dengan Design?
Have you ever noticed that the colors of the printed document are not the same as those of the design shown on your screen? Well, this is because of the differences between how a digital screen displays colors and how a printer produces them in the physical form. Here are some reasons why there is a difference in color between the printed document and design:
Color differences between RGB and CMYK
RGB (Red, Green, Blue) and CMYK (Cyan, Magenta, Yellow, Key or Black) are two different color models. RGB is used for digital devices like computer displays and televisions, while CMYK is used for printed materials. RGB colors are additive and produce different colors by adding light, while CMYK colors are subtractive and create different colors by absorbing light.
When you design on an RGB screen, you will see the colors that are made up of all three colors: Red, Green, and Blue. Conversely, when printed on a CMYK printer, it uses four separate inks to produce colors: Cyan, Magenta, Yellow, and Black. So, when colors are converted from RGB to CMYK mode, the color will change slightly – this explains why the printed color appears different from the screen color.
Printer calibration and ink types
Another reason for differences in color can be attributed to the calibration of the printer and the type of ink used in the printing process. Each printer has its own color calibration, wherein it adjusts the color output based on factors such as the type of paper, ink density, and humidity. The type of ink also plays a crucial role in the final output, as some inks can produce better results than others. Therefore, it is important to calibrate your printer and use the correct type of ink in order to produce accurate color results.
