Screens Control List

Purpose

The Screens Control List provides a central dashboard showing the status of all screens (by mesh count) in the factory
As well as providing an overview of the current state of TOT's screen inventory, this layout aids decision making as to which mesh counts require replenishing when organizing a “flag for reclaim” or ordering a batch of re-stretches

Accessing the Screens Control List

Within strokeone Screens menu, select Screens Control

Layout Content

Once opened, the layout displays information (by mesh count / sku) about the quantity of screens in each status of their life cycle.

The layout has two main sections

The top section lists all screens (frame with mesh) and their balances.
The bottom section details un-stretched frames. (mesh not present)

Each screen (mesh count / sku) is recorded as a separate line record containing the following information

Field	Type	Explanation	Extra Details
Sort	Number	A manually entered number field to aid with the sort order of the SKUs
SKU	Number	A unique system generated number that relates the FRAME TYPE & MESH together.
Description	Text	A text description of the Mesh count and Frame Type
Flagged for Reclaim	Number	The total number of screens that have been flagged as available for reclaim. Until these screens sets have been pulled out from archive this number is still include within the “number in use” field and the location filing references remain intact.
Expected	Number	The number of new screens or re-stretches that are currently on order.	When an order for screen is sent this number is credited by the Qty ordered. When screens are booked in, the QTY received is debited from here and credited into available
PO Lines	Button	Clocking this will show any outstanding purchase orders for this SKU
Available	Number	The number of screens that have been pulled out of archive and been made available for reclaim. These frames are no longer related to a screen set and are accounted for as if they have already been reclaimed. New and re-stretched frames are also treated in the same way because they have to be de greased which is part of the reclamation process.	Credited when screen sets are administered as reclaimed or when screens ordered on a purchase order are booked in. It is debited when screens are administered as coated.
Coated	Number	Total number of coated screens by mesh count which are ready for stencil making
Coat	Button	Clicking this will prompt a dialog box to record how many screens have been coated	Qty specified here will debit the Available balance and credit the coated balance
Stencils Required	Number	The total number of screens that require making to cover all production jobs that don’t yet have their stencils manufactured	Refresh triggered by Calculate Stencils Button
Calculate Stencils Required	Button	Stencils Required number is not calculated in real time. Clicking this button will recalculate the total for the SKU
Coated Minus Required	Number	The total qty of this screen type that will be ready for use once the current required screen total has been met	Think of this as the buffer / reserve. If negative it means there is a coated shortage Note: The value shown here is only updated when the Calculate stencils required button is clicked,
Total in Use	Number	Total number of coated screens by mesh count.	When screen sets are administered as reclaimed, this number is debited, and the available balance credited
Split from Coated	Button	If a coated screen splits, click this button and record the qty that split	This action debits the coated balance and credits the splits pool for the related frame size
Split from Available	Button	If a non coated screen splits, click this button and record the qty that split	This action debits the available balance and credits the splits pool for the related frame size
Screen Adjust	Button	Allows the user to set any of the following balances Flagged for Reclaim Expected Available Coated Total In use	Only experience users should adjust figure.
Select	Button	Allows the SKU to be selected	Selected SKU's can be added and then a New PO from Selection raised to order them

Screen Frame Splits Pool Information

* This section is undergoing review so content is not verified **

The number of frames (by frame type) available for re-stretching can be seen below the screen frame split pool sub summary at the bottom of the screen control list.

The information here contains three quantities

In house total: the total due to be dealt with internally

Collected: the quantity of frames which have been collected and are currently out for re-stretch

Note: these numbers are not currently accurate and their inclusion / functionality is scheduled for review in forthcoming system replacement.

Understanding Screen Control List numbers via an example

The following example is the life cycle of a screen against one mesh count.

The below screen shot has been filtered down to reflect the life cycle of a STD 49

Ordering New Screens

For our example we want to order a quantity of 10 new stretched frames of 49 Std.

So:-

Choose Select
Choose New PO From Selected
This will open the PO form layout with this selection automatically input.

Enter the Supplier and Contact (example pyramid/ dean smith)
Enter Internal Contact (example Peter Joyce)
Enter the Quantity Ordered(example 10) and Unit Cost for the product (example £25)

Once the order is sent to the supplier - the PO order status updates from Red > Purple (Sent)
Note - this triggers the expected balance to update on the screens control list
When the PO arrives the Goods In department will acknowledge receipt and send the Internal Contact an email with a temporary Location of the stock. The PO status light will update to Yellow.
The SCREEN CONTROL LIST will be undisturbed as no goods have been confirmed in yet.
Next, a member of staff from the screen room will check the goods received against the PO and book them in. Depending on the Qty received, this may be a partial or full book in
Importantly for the screens control list, the qty booked in will debit the Expected and credit the Available balances
If the full qty ordered is received, the PO status light will update to Green (completed). By contrast if less than qty ordered received, the status will update to Amber.
The following example screenshot shows the receipt of 8 of the screens ordered against and order of 10

Note how PO line status updates to Amber; as does the PO status light.
In terms of the Screens Control list, lets see the effect:-

Note how Expected has debited by the 8 received, whilst Available has been credited by the same.

De greasing

De greasing the received screens in the next process - but there is no interaction with the software for this step.

Coating

Once de greased & dried, the screens are ready for coating. As each batch of screens are coated, they need to recorded as such on the Screens Control List:-

Select Coated button beside the Std 49. In the prompt for how many have been coated enter the qty and OK (we will use 5 as an example)
Note the effect on the screens control balances

Coated balance credited by qty coated; Available balance debited by same QTY. We can also see Coated minus required now populates.
The coated screens are now ready for usage (i.e. ready to be imaged / exposed ) in stencil manufacture

Accounting for Splits

At any stage during the life cycle of a screen a mesh may become unfit for use. Most of the time this will result in accidental damage and present itself in the form of a SPLIT.

If it is not fit for purpose (i.e. the tension is insufficient or it is stained in a way that will compromise the making of new stencil) it can be deliberately damaged and relocated to the SPLIT POOL ready to be sent out for re-stretch.

SPLITS can happen at a JOB level & a NON JOB level.

Job Related Splits

Once a Stencil set has been manufactured and electronically accounted for it is considered to be at JOB level.

If any SPLITS occur at this point, they need to be accounted for within the TECH SPEC. This will be covered elsewhere in training

Non job related splits

Splits that occur in either the Available (brand new screens or those marked as reclaimed) or Coated statuses are non job related.

These are electronically accounted for in the Screens Control List by using the corresponding Splits from <status> button

The process / accounting is summarised in the first section of this topic - but essentially you specify the quantity of the SKU that has split - and the current status will be debited by that Qty and the corresponding Split pool for that frame size will be credited.

Dealing with Splits

The split pool will debit (by frame type) by any purchase order lines (for the same frame type / mesh count) that are set as Re-stretch. Additionally, the same SKU (frame mesh count) Expected balance will credit as soon as the PO is sent.

Note: It is not possible for the software to handle a purchase order with both re-stretches and new frames for the same mesh count. To work around this limitation, raise 2 PO's - one for restretch and one for new frames
